[PATCH 00/10] x86: Use the generic math implementations
- From: "H.J. Lu" <hjl dot tools at gmail dot com>
- To: libc-alpha at sourceware dot org

- Subject: [PATCH 00/10] x86: Use the generic math implementations
- Authentication-results: sourceware.org; auth=none
The new generic math implementations are faster than the current assembly
versions on i686 and x86-64. This series of patches replaces the x86
assembly versions with the generic math implementations and enables FMA
for x86-64.
H.J. Lu (10):
x86-64: Replace assembly versions of e_expf with generic e_expf.c
i386: Replace assembly versions of e_expf with generic e_expf.c
x86-64: Add exp2f with FMA
i386: Replace assembly versions of e_exp2f with generic e_exp2f.c
i386: Replace assembly versions of e_logf with generic e_logf.c
x86-64: Add logf with FMA
x86-64: Add log2f with FMA
x86-64: Add powf with FMA
i386: Replace assembly versions of e_log2f with generic e_log2f.c
i386: Replace assembly versions of e_powf with generic e_powf.c
