A bit of debugging leads to following findings:
build_common_builtin_nodes() defines supported complex mul/div functions
depending on lang_hooks.types.type_for_mode(). This langhook defaults to
c_common_type_for_mode().

These missing complex types should probably be defined in i386.c (line 17710),
alongside __float128 and __float80 definitions.

Try compiling:
c128 foo (c128 x, c128 y)
{
typedef _Complex float __attribute__((mode(TC))) c128;
x *= y;
return x;
}
This will most likely also crash at higher optimization levels.

Nope. That one doesn't ICE. The backtrace for the ICE my code in

This works for me with powerpc64-linux-gnu which has a TCmode.
I think the reason why it is only triggered with -std=c99/-std=gnu99 is because
__multc3 is only called then. __multc3 returns a TCmode. So you most li
