--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Interestingly compiling the preprocessed source with a arm cross from x86-64
does not show the problem with GCC trunk (where I happen to have a built cross
lying around). -ftime-report there shows
uninit var analysis : 0.01 ( 0%) 1400 ( 0%)
TOTAL : 18.00 277M
The uninit code didn't see any changes since GCC 14 (surrounding optimization
of course could).
I can confirm this on the GCC 14 branch with a cross. We're doing analysis
in typeFromString. GCC 15 isn't affected either. It would be nice to know
what fixed this.
