On irc we tracked down the confusion. This is about the other patch
"Use builtin bool instead of creating new bool types for
ComparisonExpr". But rebased on top of current master. Which includes
the testcase rust/compile/torture/ifunaryexpr.rs
So the above failures where:
FAIL: rust/compile/torture/ifunaryexpr.rs -O0 (internal compiler error)
FAIL: rust/compile/torture/ifunaryexpr.rs -O0 (test for excess errors)
FAIL: rust/compile/torture/ifunaryexpr.rs -O1 (internal compiler error)
FAIL: rust/compile/torture/ifunaryexpr.rs -O1 (test for excess errors)
FAIL: rust/compile/torture/ifunaryexpr.rs -O2 (internal compiler error)

FAIL: rust/compile/torture/ifunaryexpr.rs -O3 -g (internal compiler error)

FAIL: rust/compile/torture/ifunaryexpr.rs -O2 -flto -fno-use-linker-plugin

FAIL: rust/compile/torture/ifunaryexpr.rs -O2 -flto -fno-use-linker-plugin

FAIL: rust/compile/torture/ifunaryexpr.rs -O2 -flto -fuse-linker-plugin
-fno-fat-lto-objects (internal compiler error)
FAIL: rust/compile/torture/ifunaryexpr.rs -O2 -flto -fuse-linker-plugin
-fno-fat-lto-objects (test for excess errors)
Now having replicated it locally the rust.log shows:
/srv/gccrs/gccrs/gcc/testsuite/rust/compile/torture/ifunaryexpr.rs: In function
'main':
/srv/gccrs/gccrs/gcc/testsuite/rust/compile/torture/ifunaryexpr.rs:8:5: error:

/srv/gccrs/gccrs/gcc/testsuite/rust/compile/torture/ifunaryexpr.rs:8:5:

0xab454d symbol_table::finalize_compilation_unit()
../../gccrs/gcc/cgraphunit.c:2514
So, my patch created bad gimple. I'll try to track it down.
Cheers,
Mark
