Bug#1056399: libcryptx-perl: invalid opcode in CryptX.so
Control: severity +1 serious
Control: patch
Dear maintainer,
while looking at the bug I recognized, that the AMD Athlon(tm) II X2
255 Processor is not capable to handle SSE4.1 opcodes. The SSE4.1 and
SSE4.2 support by AMD CPUs was introduced later.
I rebuild the Package without these flags (-msse4.1 / -maes) and
everything works as expected. I also removed the -maes flag, since AES
is, like SSE4.1, is not part of the Debian amd64 architectural
baseline. Patch is attached.
Regards
Benedikt Spranger

Subject: [PATCH] Step back to Debian architectural baseline
libcryptx-perl is build with the compiler flags -sse4.1 and -maes.
SSE4.1 is supported by Intel CPUs, but not by all AMD CPUs. AMD CPUs
support SSE4a, which is not supported by Intel CPUs. The Debian
architectural baseline therefore states:
amd64 x86_64 with no optional extensions (psABI baseline). The
core specification includes MMX, SSE and SSE2 so these
are OK, but SSE3 and up are not guaranteed.
See psABI (Table 3.1: Micro-Architecture Levels) for
amd64 ABI level.
Remove the SSE4.1 and AES compiler flags.
