| Carlos O'Donell | 2018-01-30 17:14:23 UTC | Doc Text | Previously, the dynamic loader in the GNU C library (glibc) contained an optimization which avoided saving and restoring vector registers for 64-bit Intel and AMD architectures. Consequently, applications compiled for these architectures and using unsupported vector registers for passing function arguments, not adhering to the published x86-64 psABI specification, could fail and produce unexpected results. This update changes the dynamic loader to use the XSAVE/XSAVEC context switch CPU instructions, preserving more CPU state, including all vector registers. As a result, applications using vector registers for argument passing, in ways which are not supported by the x86-64 psABI specification, work again. | |
