Lu Date: Mon Feb 28 15:18:04 2022 -0800 Clear currently_expanding_gimple_stmt properly commit a5883ba0de68efad36db145e75c86394d8bd44ea Author: Michael Matz Date: Tue Nov 24 15:37:32 2009 + introduced currently_expanding_gimple_stmt, which was set and cleared in expand_gimple_basic_block when expanding gimple statement to RTL. But it isn't cleared when expand_gimple_basic_block returns inside the loop. PR middle-end/104721 * cfgexpand.cc (expand_gimple_basic_block): Clear currently_expanding_gimple_stmt when returning inside the loop.

Something like make_temp_override in the C++ FE. Then next time somebody adds an early return it wouldn't need to be adjusted.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104721 --- Comment #3 from H.J. Lu --- (In reply to Michael Matz from comment #2) > Is there a testcase where you noticed this, or was it just reading code? I am working on a patch to check currently_expanding_gimple_stmt != NULL in i386 backend. At -O2, currently_expanding_gimple_stmt isn't NULL outside of gimple to RTL expansion when compiling libgomp.fortran/reduction1.f90. I tracked it down to expand_gimple_basic_block.
