Chris Lattner 1877ec9b02 For functions that use vector registers, save VRSAVE, mark used ... registers, and update it on entry to each function, then restore it on exit. This compiles: void func(vfloat *a, vfloat *b, vfloat *c) { *a = *b * *c + *c; } to this: _func: mfspr r2, 256 oris r6, r2, 49152 mtspr 256, r6 lvx v0, 0, r5 lvx v1, 0, r4 vmaddfp v0, v1, v0, v0 stvx v0, 0, r3 mtspr 256, r2 blr GCC produces this (which has additional stack accesses): _func: mfspr r0,256 stw r0,-4(r1) oris r0,r0,0xc000 mtspr 256,r0 lvx v0,0,r5 lvx v1,0,r4 lwz r12,-4(r1) vmaddfp v0,v0,v1,v0 stvx v0,0,r3 mtspr 256,r12 blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26733 91177308-0d34-0410-b5e6-96231b3b80d8		2006-03-13 21:52:10 +00:00
