Support AES-XTS AVX512/VAES
Support AES-GCM AVX512/VAES
Support AES-ECB/CBC/CTR AVX512/VAES/AVX1/AES-NI.
Remove code from aes_asm.S/aes_asm.asm
Add CPU defines for AVX512 and VAES
Updated ASM files with new defines for AVX512.
Added support for printing out the new CPU Id flags in benchmark.
Added new files to Windows projects.
aes.c: Supports ECB/CBC/CTR in assembly. Supports calling AVX512/VAES assembly.
Refactors the output format of generated assembly files across all
platforms
(x86_64, ARM AArch64, ARMv8-32, Thumb2, PowerPC) for consistency and
correctness.
Changes
Data constant consolidation
- Pack multiple values per directive line (e.g., 4× .long or 8× .short
per
line) instead of one value per line, reducing file sizes significantly
- Normalize hex literal formatting: 64-bit values use full 8-byte
zero-padded
form (e.g., 0x0000000003ffffff instead of 0x3ffffff)
x86_64 assembly
- Use decimal immediate values for shift counts (e.g., $1 instead of
$0x01)
- .asm (MASM): use hex notation consistently for data constants;
update ALIGN
values to match data width (e.g., ALIGN 32 for 256-bit aligned data)
ARM .S files
- Move .type directive before .section for data objects (correct
ordering per
ELF convention)
ARM/Thumb2 inline C (_c.c) files
- Replace asm( with __asm__( for register variable constraints (better
portability)
- Add XALIGNED(8) attribute to constant lookup tables used in inline
asm
- Remove redundant #include <stdint.h> and
<wolfssl/wolfcrypt/libwolfssl_sources.h> headers
Files affected: 71 assembly and companion C files across
wolfcrypt/src/,
wolfcrypt/src/port/arm/, covering AES, ChaCha, Poly1305,
SHA-256/512/3,
Curve25519, ML-KEM, ML-DSA, and SP math routines.
Specific compress key code for P521 doesn't need a n square function.
Fixing generation of x86_64 ASM scripts resulted in adding carriage
return to chacha_asm.S.
For the CMake and autotools flows, enabling user_settings.h will define the
macro WOLFSSL_USER_SETTINGS_ASM. This will cause the generated
user_settings_asm.h to be included in the .S assembly files. If the user is
building without autotools or CMake, these files will include user_settings.h
directly, unless WOLFSSL_USER_SETTINGS_ASM is defined.
Added new x86 assembly for AES.
AES-CBC decrypt only 4 blocks at a time (not 6 or 8) due to reduces
register count.
GCM implementation for AVX2, AVX1 and AESNI only.
Disabled looking for other assembly files for x86.
For user_settings.h builds, .S assembly files need to include user_settings.h
in order to get the defines used by the build. However, a user_settings.h may
contain code only understood by a C compiler and not the assembler (e.g. a
typedef). This commit makes it so our autotools and CMake builds produce a file
user_settings_asm.h when doing a user_settings.h build. This generated header
contains only the preprocessor directives from the user_settings.h. As a result,
it can be safely included by our assembly code files.
Add x86_64 assembly code:
- BMI2
- AVX2 (using ymm, slower than BMI2)
- AVX2 of 4 similtaneous hashes
Add SHAKE128 functions and tests.
Add Absorb and Squeeze functions for SHAKE128 and SHAK256 and tests.
Add doxygen for SHA-3 and SHAKE functions.
Update other generated x86_64 assembly files to include settings.h.
