GCC may emit a call to __ashlti3 for 128-bit left shifts when
compiling code that uses unsigned __int128, such as OpenSSL Curve448
code in CryptoPkg. The LoongArch64 firmware build does not link against
libgcc, so provide the helper from CompilerIntrinsicsLib.
Implement __ashlti3 using the LoongArch64 ABI: the low and high 64-bit
halves are passed in $a0 and $a1, the shift count is passed in $a2, and
the result is returned in $a0 and $a1.

MdePkg: Add PE Target Support to AArch642026-01-15T17:10:46+00:00Oliver Smith-Dennyosde@microsoft.com2025-12-17T17:59:01+00:00urn:sha1:a9faf07bc089c75b0e3e1bf05b2117240a1fafb1
PE targets do not support the ELF style .type, .size,
or .previous directives and have different name mangling,
so this commit updates MdePkg AArch64 code to support
PE targets.
PE targets also don't support the fixup_aarch64_ldr_pcrel_imm19
relocation type, which is created doing ldr <literal>. This
introduces a new set of macros, LDR_LIT nad LDR_LIT_TMP,
which will use the direct ldr for ELF targets and ADRP/LDR
for PE targets, because the ADRP/LDR version requires
4KB alignment, which is guaranteed on CLANGPDB.

MdePkg: Remove ARM32 Support from CompilerIntrinsicsLib2025-09-25T22:04:10+00:00Oliver Smith-Dennyosde@microsoft.com2025-09-15T21:15:45+00:00urn:sha1:bc31103006cd468ca604f50c18cca7d73be27655
edk2 is dropping support for the ARM32 architecture. This
commit removes ARM32 code from CompilerIntrinsicsLib.

MdePkg: Move CompilerIntrinsicsLib from ArmPkg2024-09-12T19:36:59+00:00Oliver Smith-Dennyosde@linux.microsoft.com2024-08-05T17:25:07+00:00urn:sha1:8f74b95a21cf106fa4eb4932e22b404c57297ba2
As per the emailed RFC in
https://edk2.groups.io/g/devel/topic/rfc_move/107675828,
this patch moves CompilerIntrinsicsLib from ArmPkg to
MdePkg as this library provides compiler intrinsics, which
are industry standard.
This aligns with the goal of integrating ArmPkg into existing
packages: https://bugzilla.tianocore.org/show_bug.cgi?id=4121.
The newly placed CompilerIntrinsicsLib is added to MdeLibs.dsc.inc
as every DSC that builds ARM/AARCH64 needs this library added. The
old location is removed from every DSC in edk2 in this commit also
to not break bisectability with minimal hoop jumping.
