If one dumps the bb, one finds a call to GOMP_SIMD_VF.
Using the following patch on top of yours fixes the issue for the reduced test
case and for the compilation to the *.o files in the real-world code:
--- a/gcc/tree-inline.c
+++ b/gcc/tree-inline.c
@@ -4066,5 +4070,5 @@ expand_call_inline (basic_block bb, gimple stmt,
copy_body_data *id)
/* From here on, we're only interested in CALL_EXPRs. */
- if (gimple_code (stmt) != GIMPLE_CALL)
+ if (gimple_code (stmt) != GIMPLE_CALL || gimple_call_internal_p (stmt))
goto egress;
* * *
Unfortunately, the lto1 phase still fails for the big code. For that one, I
get:
