Can the decision to build with gcc 4.4 instead of disabling the i386
assembly optimisations now be reconsidered? Perhaps with a view to
making this change when jessie opens?
Note that AFAICT the optimisations are only enabled when __i386__ is
defined, so amd64 has been relying on gcc's optimisation for the
portable C equivalent anyway. I think it's also reasonable to doubt
the
usefulness of the assembly that's being used, since it was clearly
designed and compared against an older version of gcc, and using a
newer
gcc invalidates any assumptions that the assembly optimisations
provide
any performance benefit anyway.
There is a regression risk, but only if the underlying code is broken.
Since the test suite detected the original problem, I think it's
reasonable to consider it to have adequate coverage to manage the
risk.
So can we now define TAOCRYPT_DISABLE_X86ASM and drop the use of
gcc-4.4 please?
+1 from me. I have also started working on packing a non-embedded
cyassl for Jessie, and I hope to link MySQL 5.6 against it. Presumably
MariaDB can do the same.
