Subject: [PATCH] Fix building AArch32 CE implementations when target is ARMv6
|
|
arch
|
|
|
|
* cipher/cipher-gcm-armv8-aarch32-ce.S: Select ARMv8 architecure.
|
|
* cipher/rijndael-armv8-aarch32-ce.S: Ditto.
|
|
* cipher/sha1-armv8-aarch32-ce.S: Ditto.
|
|
* cipher/sha256-armv8-aarch32-ce.S: Ditto.
|
|
* configure.ac (gcry_cv_gcc_inline_asm_aarch32_crypto): Ditto.

Raspbian distribution defaults to ARMv6 architecture thus 'rbit'
|
|
instruction is not available with default compiler flags. Patch
|
|
adds explicit architecture selection for ARMv8 to enable 'rbit'
|
|
usage with ARMv8/AArch32-CE assembly implementations of SHA,
|
|
GHASH and AES.
