H.J. Lu	4e1e2f4247	Support mixed SSE/AVX audit and check AVX only once. ... This patch fixes mixed SSE/AVX audit and checks AVX only once in _dl_runtime_profile. When an AVX or SSE register value in pltenter is modified, we have to make sure that the SSE part value is the same in both lr_xmm and lr_vector fields so that pltexit will get the correct value from either lr_xmm or lr_vector fields. AVX-enabled pltenter should update both lr_xmm and lr_vector fields to support stacked AVX/SSE pltenter functions.	2009-08-08 10:54:42 -07:00
Ulrich Drepper	d7bd7a8ae8	Secure AVX changes for auditing code. ... The original AVX patch used a function pointer to handle the difference between machines with and without AVX support. This is insecure. A well-placed memory exploit could lead to redirection of the execution. Using a variable and several tests is a bit slower but cannot be exploited in this way.	2009-07-15 17:41:36 -07:00
