> For a reference, this is the patch I am testing:

Yes, this patch fixes stdarg failures from [1] with preliminary test:

FAIL: gcc.c-torture/execute/stdarg-1.c execution,  -O3 -fomit-frame-pointer 
FAIL: gcc.c-torture/execute/stdarg-1.c execution,  -O3 -g 
FAIL: gcc.c-torture/execute/stdarg-4.c execution,  -O1 
FAIL: gcc.c-torture/execute/stdarg-4.c execution,  -O2 
FAIL: gcc.c-torture/execute/stdarg-4.c execution,  -O3 -fomit-frame-pointer 
FAIL: gcc.c-torture/execute/stdarg-4.c execution,  -O3 -g 
FAIL: gcc.c-torture/execute/stdarg-4.c execution,  -Os 
...
FAIL: gcc.dg/tree-ssa/stdarg-2.c scan-tree-dump stdarg "f15: va_list escapes 1,
needs to save all GPR units and all FPR units"

I will start full bootstrap and regression test over night.
