--- Comment #3 from vries at gcc dot gnu.org --- Before postponing expansion of va_arg to pass_stdarg, we had at pass_stdarg: ... f2: va_list escapes 0, needs to save 4 GPR units and all FPR units. ... On one hand, the optimization in pass_stdarg has regressed. OTOH, that hasn't brought a regression in code generation. So I'm not sure if this should be marked as a '6 Regression', and/or tagged with missing optimization.
