Subject: [PATCH 3/8] Fix SIMD support on IBM z13
|
|
|
c34203 |
|
|
|
c34203 |
The header file atlas_simd.h contained a syntax error and a few functional
|
|
|
c34203 |
errors that affected IBM z13. It prevented any SIMD kernels from being
|
|
|
c34203 |
compiled successfully for that platform. This is fixed. The macro
|
|
|
c34203 |
vec_madd is avoided, because some GCC versions don't implement it
|
|
|
c34203 |
correctly; the equivalent GCC builtin __builtin_s390_vec_madd is used
|
|
|
c34203 |
instead.
