Turns out we actually need setjmp in one of gnu-efi's prominent
users, and it seems to make more sense to put it here than in
the application.
All of these are derived from the Tiano code, but I re-wrote the
x86_64 one because we use the ELF psABI calling conventions instead
of the MS ABI calling conventions. Which is to say you probably
shouldn't setjmp()/longjmp() between functions with EFIAPI (aka
__attribute__((ms_abi))) and those without.

Enable out-of-tree building
This patch enables building gnu-efi outside of the source tree.
That in turn enables building for multiple architectures in parallel.
The build directory is controlled by the OBJDIR make variable. It
defaults to the value of ARCH, and can be overridden from the command
line.
This patch also cleans up some doubled slashes between INSTALLROOT
and PREFIX.

This patch makes generating releases from git a very simple process; you
simply edit the makefile's "VERSION" line to the new version, commit
that as its own commit, and do: "make test-archive". That'll make a
file in the current directory gnu-efi-$VERSION.tar.bz2 , with its top
level directory gnu-efi-$VERSION/ and the source tree under that.
Once you've tested that and you're sure it's what you want to release,
you do "make archive", which will tag a release in git and generate a
final tarball from it. You then push to the archive, being sure to
include the tag:
git push origin master:master --tags
And upload the archive wherever it's supposed to go.

Subject: [PATCH] Add support for 32-bit ARM
This adds support for 32-bit ARM using an approach similar to the one used for
64-bit ARM (AArch64), i.e., it does not rely on an objcopy that is aware of EFI
or PE/COFF, but lays out the entire PE/COFF header using the assembler.
In the 32-bit ARM case (which does not have a division instruction), some code
has been imported from the Linux kernel to perform the division operations in
software.

Subject: [PATCH 2/4] Add support for cross compilation
This changes the logic that defines ARCH (and HOSTARCH) to take CROSS_COMPILE

is on the path rather than hardcoded in /usr/bin.
This results in the build doing the right thing if CROSS_COMPILE is set in the
environment and no ARCH or prefix options are passed to make, aligning it with
most other CROSS_COMPILE compatible projects.

Subject: [PATCH] always observe EFIAPI calling convention when calling
STO.SetAttribute
We have to consider the following cases wrt. the PRINT_STATE.Output and
PRINT_STATE.SetAttr EFIAPI function pointers, especially when building for
x86_64 with gcc:
(1) The compiler is new enough, and EFIAPI actually ensures the Microsoft
calling convention. In this case everything happens to work fine even
if we forget uefi_call_wrapper(), because the wrapper would expand to
a normal C function call anyway.
(2) Otherwise (ie. gcc is old), EFIAPI expands to nothing, and we must
take into account the called function's origin:
(2a) If the callee that is declared EFIAPI is *defined* inside gnu-efi,
then EFIAPI means nothing for the callee too, so caller and callee
only understand each other if the caller intentionally omits
uefi_call_wrapper().
(2b) If the callee that is declared EFIAPI is defined by the platform
UEFI implementation, then the caller *must* use
uefi_call_wrapper().
The PRINT_STATE.Output EFIAPI function pointer is dereferenced correctly:
the PFLUSH() distinguishes cases (2a) from (2b) by using IsLocalPrint().
However use of the PRINT_STATE.SetAttr EFIAPI function pointer is not
always correct:
- The PSETATTR() helper function always relies on the wrapper (case (2b)).
This is correct, because PRINT_STATE.SetAttr always points to a
platform-provided function.
- The DbgPrint() function contains two incorrect calls: they mistakenly
assume case (2a) (or case (1)), even though the pointer always points to
a platform function, implying (2b). (The error is masked in case (1).)
Fix them.

The prototype of DbgPrint() is incorrect, at the end of "inc/efidebug.h".
Consequently, when your program calls DbgPrint() via the DEBUG() macro,
it fails to set up the stack correctly (it does not pass the arguments
through the ellipsis (...) according to the EFIAPI calling convention).
However, va_start() inside DbgPrint() *assumes* that stack.

you might miss that you should be more concered about.
You could work around it through vigorous typecasting

Disable MMX and SSE
GCC 4.8.0 adds some optimizations that will use movups/movaps (and use
%xmm* registers) when they're faster, and of course that won't work at
all since UEFI firmwares aren't guaranteed to initialize the mmx/sse
instructions.
This will be even more annoying, since most UEFI firmwares don't
initialize the #DE or #UD trap handlers, and your backtrace will be a
random path through uninitialized memory, occasionally including
whatever address the IDT has for #UD, but also addresses like "0x4" and
"0x507" that you don't normally expect to see in your call path.

fix parameter-passing corruption on x86_64 for >= 5 args
On x86_64 without HAVE_USE_MS_ABI support, uefi_call_wrapper() is a
variadic function. Parameters >=5 are copied to the stack and, when
passed small immediate values (and possibly other parameters), gcc
would emit a movl instruction before calling uefi_call_wrapper(). As a
result, only the lower 32b of these stack values are significant, the
upper 32b potentially contain garbage. Considering that
uefi_call_wrapper() assumes these arguments are clean 64b values
before calling the efi_callX() trampolines, the latter may be passed
garbage. This makes calling functions like
EFI_PCI_IO_PROTOCOL.Mem.Read()/Write() or BS->OpenProtocol() quite
unreliable.
This patch fixes this by turning uefi_call_wrapper() into a macro that
allows to expose the efi_callX() trampoline signatures to the callers,
so that gcc can know upfront that it has to pass all arguments to
efi_callX() as clean 64b values (eg. movq for immediates). The
_cast64_efi_callX macros are just here to avoid a gcc warning, they do
nothing otherwise.

- Removes the ElfW() macro usage from reloc_ia32.c and reloc_x86_64.c. These
macros only exist in link.h on Linux. On FreeBSD, the equivalent macro is
__ElfN(). But the macro usage is redundant. You're only going to compile the
ia32 file for IA32 binaries and the x86_64 file for X64 binaries. If you had
just one file built for both cases, then using the macro might make more
sense.
- Removes the "#define foo_t efi_foo_t" macros from reloc_ia32.c and
reloc_x86_64.c.
- Modifies inc/x86_64/efibind.h and inc/ia32/efibind.h to use the new
definitions for uint64_t, int64_t and int8_t. The 64-bit types are now defined
as:
typedef int __attribute__((__mode__(__DI__))) int64_t;
typedef unsigned int __attribute__((__mode__(__DI__))) uint64_t;
This removes the conflict between the host types dragged in by elf.h and the
type definitions in efibind.h that made the #define foo_t efi_foo_t" hack
necessary. Also, int8_t is now defined as signed char instead of just char
(assuming char == signed char is apparently not good enough).
- Also modifies these files to use stdint.h instead of stdint-gcc.h. It's
unclear if this is completely correct, but stdint-gcc.h is not present with
all GCC installs, and if you use -std=c99 or later you will force this case to
be hit. This also can break clang, which doesn't have a stdint-gcc.h at all.
- Removes the #include of <link.h> from reloc_ia32.c and reloc_x86_64.c (since
with the previous changes it's not needed anymore).
- Places the #include of <elf.h> after #include <efi>/#include <efilib.h> so
that we know the types will always be defined properly, in case you build on a
system where <elf.h> doesn't automatically pull in the right header files to
define all the needed types. (This actually happens on VxWorks. It's harmless
elsewhere. If you don't care about VxWorks, you can leave this out.)
- Modifies setjmp_ia32.S and setjmp_x86_64.S so to change "function" to
@function. The clang compiler doesn't like the former. Clang and GCC both like
the latter.
- Modifles Make.defaults so that if ARCH is detected as "amd64," it's changed
to "x86_64." It happens that uname -m on 64-bit FreeBSD reports the former
rather than the latter, which breaks the build. This may also be the case on
some other OSes. There's a way to force uname(1) to return x86_64 as the
machine type, but this way is a little friendlier.
- Creates gnuefi/elf_ia32_fbsd_efi.lds which specifies the object file type as
elf-ia32-freebsd. This is required for building on FreeBSD/i386, not just
FreeBSD/amd64.
- Modifies apps/Makefile to always use
$(TOPDIR)/gnuefi/elf_$(ARCH)_fbsd_efi.lds when building on either 32-bit or
64-bit FreeBSD instead of just for the x86_64 case.
- Changed LDFLAGS in Make.defaults to include --no-undefined. This will cause
linking to fail if there are any unsatisfied symbols when creating foo.so
during any of the app builds, as opposed to just silently succeeding and
producing an unusable binary.
- Changed CFLAGS to include -ffreestanding -fno-stack-protector -fno-stack-
check. This prevents clang from inserting a call to memset() when compiling
the RtZeroMem() and RtSetMem() routines in lib/runtime/efirtlib.c and guards
against the native compiler in some Linux distros from adding in stack
checking code which relies on libc help that isn't present in the EFI runtime
environment.
This does the following:
- Cleans up the ia32 and x86-64 relocation code a bit (tries to break the
dependency between the host ELF headers and the EFI runtime environment)
- Avoids the dependency on stdint-gcc.h which may not always be available
- Allows GNU EFI to build out of the box on both FreeBSD/i386 and
FreeBSD/amd64
- Allows GNU EFI to build out of the box with either GCC or clang on
FreeBSD/i386 and FreeBSD/amd64 9.0 and later.
- Makes things a little easier to port to VxWorks
- Avoids creating un-runable binaries with unresolved symbol definitions
(which can be very confusing to debug)

* Change from Peter Jones <pjones@redhat.com>
- Previously we were incorrectly passing 3 functions with
the System V ABI to UEFI functions as EFI ABI functions.
Mark them as EFIAPI so the compiler will (in our new
GNU_EFI_USE_MS_ABI world) use the correct ABI.
- These need to be EFIAPI functions because in some cases
they call ST->ConOut->OutputString(), which is an EFIAPI
function. (Which means that previously in cases that
needed "cdecl", these didn't work right.)
- If the compiler version is new enough, and GNU_EFI_USE_MS_ABI
is defined, use the function attribute ms_abi on everything
defined with "EFIAPI". Such calls will no longer go through
efi_call*, and as such will be properly type-checked.
- Honor PREFIX and LIBDIR correctly when passed in during the build.
- Add machine type defines for i386, arm/thumb, ia64, ebc, x86_64.
- __STDC_VERSION__ never actually gets defined unless there's a
--std=... line. So we were accidentally defining lots of c99
types ourself. Since it's 2012, use --std=c11 where appropriate,
and if it's defined and we're using gcc, actually include gcc's
stdint definitions.
- New test application added: route80h. This is a test program
for PciIo. It routes ioport 80h on ICH10 to PCI. This is also
useful on a very limited set of hardware to enable use of
a port 80h debug card.

* release 3.0a
* modified both IA-64 and IA-32 loader scripts to add support for the

for new versions of gcc3.x.
2001-06-20 Stephane Eranian <eranian@hpl.hp.com>
* release 3.0
* split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
* removed W2U() hack and related files to get from wide-char to unicode.
* Use -fshort-wchar option for unicode.
* restructured Makefiles now install under INSTALLROOT.
2001-04-06 Stephane Eranian <eranian@hpl.hp.com>
* incorporated patches from David and Michael Johnston at Intel
to get the package to compile for IA-32 linux target.
* Fixed ELILO to compile for Ia-32 (does not execute yet, though):
Makefile and start_kernel() function.
2001-04-06 Andreas Schwab <schwab@suse.de>
* Fixed config.c to
get the timeout directive to do something. implemented the global
root= directive.
* Fix the efi_main() to deal with the -C option properly
2001-04-05 Stephane Eranian <eranian@hpl.hp.com>
* update efi library to latest EFI toolkit 1.02 as distributed
by Intel. Fixed header + library files to compile with GCC
* merged ELI and LILO (as of gnu-efi-1.1) together, mostly
taking the config file feature of ELI.
* renamed LILO to ELILO to make the distinction
* restructured code to make it easier to understand and maintain
* fixed FPSWA driver checking and loading: we try all possible
files and let the driver itself figure out if it is the most
recent.
* added support for compression (gzip) but keep support for plain
ELF image. ELILO autodetects the format
* change the way the kernel is invoked. Now we call it in
physical memory mode. This breaks the dependency between the
kernel code and the loader. No more lilo_start.c madness.
* changed the way the boot_params are passed. We don't use the
ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory.
The address of the structure is passed to the kernel in r28
by our convention.
* released as gnu-efi-2.0
2001-04-03 David Mosberger <davidm@hpl.hp.com>
* gnuefi/reloc_ia32.c (_relocate): Change return type from "void"
to "int". Return error status if relocation fails for some
reason.
* gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section.
* gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with
non-zero exit status.
* inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit
types as that is what EFI appears to be expecting, despite the
"#pragma pack()" at the beginning of the file!
2001-03-29 David Mosberger <davidm@hpl.hp.com>
* gnuefi/reloc_ia32.c: Add a couple of defines to work around
libc/efilib collision on uint64_t et al.
(_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
* gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
2001-03-29 David Mosberger <davidm@hpl.hp.com>

* Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick
up the C compiler's stdarg.h.
* inc/stdarg.h: Remove this file. It's not correct for gcc (nor
most other optimizing compilers).
2000-10-10 Stephane Eranian <eranian@hpl.hp.com>
* cleaned up the error message and printing of those.
* added support to load the FPSWA from a file in case support is not
present in the firmware already
* fixed split_args() to do the right thing when you have leading spaces
before kernel name
* changed the argify() function to rely on \0 instead of LoadOptionSize
as the field seems to be broken with current firmware
* bumped version to 1.0
2000-10-04 David Mosberger <davidm@hpl.hp.com>
* gnuefi/reloc_ia64.S: Reserve space for up to 750 function descriptors.
* gnuefi/elf_ia64_efi.lds: Add .sdata section for small data and
put __gp in the "middle" of it.
* gnuefi/crt0-efi-ia64.S (_start): Use movl/add to load
gp-relative addresses that could be out of the range of the addl
offset.
* gnuefi/reloc_ia64.S (_relocate): Ditto.
* apps/Makefile: Remove standard rules and include Make.rules instead.
* lilo/Makefile: Ditto.
* Make.rules: New file.

.IA64.unwind_info to .data section and .rela.ctors to .rela
section.
2000-04-03 David Mosberger <davidm@hpl.hp.com>
* lilo/lilo.c (LILO_VERSION): Up version number to 0.9.
* gnuefi/elf_ia64_efi.lds: Include .IA_64.unwind and
.IA_64.unwind_info in .data segment to avoid EFI load error
"ImageAddress: pointer outside of image" error due to the .dynsym
relocations against these sections.
* ChangeLog: Moved from lilo/ChangeLogs.
* gnuefi/reloc_ia64.S: fixed typo: .space directive had constant
100 hardcoded instead of using MAX_FUNCTION_DESCRIPTORS
macro. Duh.
2000-03-17 Stephane Eranian <eranian@hpl.hp.com>
* Released 0.8
* replace the getopt.c with new version free with better license
* created a documentation file
* fix a couple of memory leaks
