On couple of locations in runtime string library (rtstr.c)
there are calls to non-runtime variant of StrLen function.
* Another issue is with formatting 1394 paths.
The F1394_DEVICE_PATH::Guid is formatted as %g, but 1394
GUID is 8 byte integer, not EFI_GUID and therefore should
be formatted as e.g. %016lx (as edk2 does).
* Beyond what's mentioned above, changed the format of the
harddrive path, so it's in line with edk2 format and spec
(2.7 errata A, chapter 10.6.1.6, table 102).

The arguments to SetMem() were wrong. Besides, SetMem() should start at
"Dest + Size" since "Size" will be smaller than "Len" if they are not
equal.

We need the x86_64 and i686 builds of .a's to be the same, and that
means we need to not have timestamps. Also force the timestamps on disk
just in case that doesn't work, because RHEL's ar /silently ignores -D/.
v2: use "ar rvD" not "ar rv -D".
It's a wonder anybody ever gets these command line options right, if
"ar rv -D libfoo.a foo.o" doesn't use deterministic mode (or
complain), but "ar rvD libfoo.a foo.o" does.
v3: Add a bunch of junk to try to set timestamps to 0 manually
For some reason I'm still getting timestamps in the .a even though ar seems to
be invoked correctly. When I do "mock -r rhel-7-build --shell" and run make
manually, they're fine. Very strange.
v4: go back to v2, the problem isn't in the make process.
"ar rDv" works just fine, but /usr/lib/rpm/redhat/brp-strip-static-archive is
calling "%{__strip} -g $for_each.a", and it's rewriting our binary from
ts/uid/gid of 0/0/0 to $epoch/$UID/$GID. Awesomely /usr/bin/strip it seems to
have 3 modes of operation:
-U: the default, which adds $epoch/$UID/$GID to your binary archive
instead of just removing stuff. Clearly the Principle of Least
Surprise is strong here.
-p: preserve the timestamp from the original .a, but add UID and GID,
because this is 1980 and people use ar(1) for archiving stuff they
might want that out of.
-D: Condescend at you in a command line error and explain that -D both
is and is not a valid option:
/usr/bin/strip: invalid option -- 'D'
Usage: /usr/bin/strip <option(s)> in-file(s)
Removes symbols and sections from files
The options are:
...
-D --enable-deterministic-archives
Produce deterministic output when stripping archives
So I agree that it's invalid, but I think we may be pronouncing that
second vowel differently. They say in-VAL-id, I say IN-vuh-lid.
Nobody should ever have to run "strace -ttt -v -f -o make.strace make all",
just to discover the problem isn't even in there.

Commit 751cbce3 fixed up a bunch of types to better match the edk2
definitions and the names in the UEFI Spec, but while doing so
inadvertantly defined things thusly:
INTERFACE_DECL(_EFI_PXE_BASE_CODE_PROTOCOL);
...
typedef struct _EFI_PXE_BASE_CODE_PROTOCOL {
...
} EFI_PXE_BASE_CODE_PROTOCOL;
...
typedef struct _EFI_PXE_BASE_CODE_PROTOCOL _EFI_PXE_BASE_CODE;
typedef struct EFI_PXE_BASE_CODE_PROTOCOL EFI_PXE_BASE_CODE;
Because EFI_BASE_CODE_PROTOCOL is declared with a typedef, and is
therefore in the type namespace rather than the struct namespace, this
results in EFI_PXE_BASE_CODE being a forward declaration of an
incomplete type. The net result is that code which dereferences any
field in the struct, even with the correct names, will not correctly
build.
This patch changes both _EFI_PXE_BASE_CODE and EFI_PXE_BASE_CODE
typedefs to inherit from struct _EFI_PXE_BASE_CODE_PROTOCOL.

Gentoo has slightly modified linker defaults: --hash-style=gnu
This means all ELF files in system have '.gnu.hash' section
but no '.hash' section.
gnuefi's ldscript did not account for it and as a result
one symbol 'ImageBase' did not resolve locally for elilo.so
and caused 'elilo' to fail to load by ia64 EFI:
Loading.: Gentoo (try new elilo)
ImageAddress: pointer is outside of image
ImageAddress: pointer is outside of image
Those two relocations come from crt0-efi-ia64.S PE32 entry point
fdescr:
```
#define IMAGE_REL_BASED_DIR64<->10
.section .reloc, "a"
data4 _start_plabel // Page RVA
data4 12 // Block Size (2*4+2*2)
data2 (IMAGE_REL_BASED_DIR64<<12) + 0 // reloc for plabel's entry point
data2 (IMAGE_REL_BASED_DIR64<<12) + 8 // reloc for plabel's global pointer
```
These refer ImageBase.
The change adds '.gnu.hash' collection (follows existing '.hash'
collection).
Tested on IA-64 by successfully booting elilo-3.16.

Following up on previous patch, I think we should move
memcpy/memset definitions to the global init.c, since MSVC does
also inserts calls to memset/memcpy for the x86_32 platform,
even when disabling standard libraries and intrinsics.
All in all, it looks like, for all platforms, we should assume
that a compiler may still insert these calls regardless.

the versions of Visual Studio that support ARM or ARM64 have that
header. Without this, uint64_t would be defined to unsigned long,
which is 32-bits in the Microsoft world.
Also fix aarch64/initplat.c so that memset/memcpy only apply
to gcc. Otherwise MSVC throws an error for __SIZE_TYPE__.
Updating this patch to v2, since it turns out MSVC will also emit
memset and memcpy intrinsics that we can use an implementation for.
This is true for both ARM and ARM64.
To make this work, I'm defining __SIZE_TYPE__ to UINTN if not
already defined.

If gnu-efi is compiled with "-march=native" on a host that supports AVX, both
gcc and clang will use AVX instructions freely which is currently not supported
and will result in a non-functional gnu-efi build (e.g. black screen, hangs).
For now, disable AVX on IA32 and x86_64 by checking first if the compiler does
actually support the appropriate flag (-mno-avx) and use it if possible.
Credit for the compiler command line to check if a flag is supported goes to
Gentoo's awesome flag-o-matic eclass, where it is taken from. Thanks.

EFI_PXE_BASE_CODE was redefined in the early commit(*) to match the
definition in EDK2. However, EFI_PXE_BASE_CODE wasn't declared
correctly. Since EFI_PXE_BASE_CODE_PROTOCOL is already an alias of
"struct _EFI_PXE_BASE_CODE_PROTOCOL", the additional struct in front of
EFI_PXE_BASE_CODE_PROTOCOL actually confused the compiler and caused
build fail. Remove the redundant struct to avoid confusion.

R_X86_64_GOTPCREL64, R_X86_64_GOTPCRELX, and R_X86_64_REX_GOTPCRELX,
which our _relocate() does not support, for extern declarations visible
to things linking against a DSO. Since we're really just building a .a
here, and *nothing* needs to be exported in the .so sense, we don't need
any of that optimization at all, there's no point in making _relocate()
know how to handle these.
Instead, this patch simply removes the visibility from everything in the
.a, which gets us back to fairly normal relative relocations that wind
up being R_X86_64_RELATIVE in the final binary, which we can handle.

I think ARM's DivU64x32() would be better located along MultU64x32()
and other calls in ARM's math.c, as having it in a header seems weird,
even with the goal of inlining it. I doubt there's much performance
to be lost from having it non-inline in math.c and it should make the
