Summary: verify_gimple fails building ada/einfo.o at -O3
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3

The patch for bug 48989 regressed BUILD_CONFIG=bootstrap-O3 ada builds on i686-
and x86_64-linux-gnu. While building stage2 we hit this error:
../../gcc/ada/einfo.adb: In function ‘Einfo.Is_String_Type.Part’:
../../gcc/ada/einfo.adb:6377:4: error: invalid conversion in gimple call

Yep. I'm going to reduce it into a testcase for gnat.dg.

Created attachment 24390
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24390
Reduced testcase for x86
Run gnatchop and compile the adb file at -O3 -gnata. Suitable for gnat.dg.

where only for the type of the LHS we know it's two-valued.
This is exposed during inlining triggered by function splitting.

I think a similar case could be constructed with restrict qualified pointers.
I have a patch.
