> I have 4 regressions in the C testsuite with -mflat on SPARC/Solaris:
And 2 regressions in 64-bit mode:
FAIL: gcc.c-torture/execute/nestfunc-6.c execution, -O1
[...]
FAIL: gcc.dg/torture/stackalign/nested-6.c -O1 execution test
[...]
Another latent problem exposed by the change. Tested on SPARC/Solaris, applied
on the mainline.
