- Subject: [committed/Darwin]: fix fetch of amd64 fpu registers
Hi,
this patch fixes a typo in i386-darwin-nat.c so that fpu registers are
correctly supplied in amd64 case.
Tristan.
2009-10-22 Tristan Gingold <gingold@adacore.com>
* i386-darwin-nat.c (i386_darwin_fetch_inferior_registers): Use
amd64_supply_fxsave for amd64. Fix the offset.
(i386_darwin_store_inferior_registers): Use amd64_collect_fxsave
for amd64.
