--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Richard Sandiford <rsand...@gcc.gnu.org>: https://gcc.gnu.org/g:25921d664242f651ed8a25b3db55093a19a5ae7b commit r16-336-g25921d664242f651ed8a25b3db55093a19a5ae7b Author: Christopher Bazley <chris.baz...@arm.com> Date: Thu May 1 22:00:42 2025 +0100 Fix BZ 119317: named loops (C2y) with debug info Named loops (C2y) could not previously be compiled with -O1 and -ggdb2 or higher because the label preceding a loop (or switch) could not be found when using such command lines. This could be observed by compiling gcc/gcc/testsuite/gcc.dg/c2y-named-loops-1.c with the provoking command line (or any minimal example such as that cited in the bug report). The fix was simply to ignore the tree nodes inserted for debugging information. Base commit is 79aa2a283a8d3327ff4d6dca77e81d5b1ac3a01e PR c/119317 gcc/c/ChangeLog: * c-decl.cc (c_get_loop_names): Do not prematurely end the search for a label that names a loop or switch statement upon encountering a DEBUG_BEGIN_STMT. Instead, ignore any instances of DEBUG_BEGIN_STMT. gcc/testsuite/ChangeLog: * gcc.dg/c2y-named-loops-8.c: New test.
