--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:bb169406cdc9e044eaec500dd742c2fed40f5488 commit r12-2831-gbb169406cdc9e044eaec500dd742c2fed40f5488 Author: Richard Biener <[email protected]> Date: Mon Aug 9 10:19:10 2021 +0200 middle-end/101824 - properly handle volatiles in nested fn lowering When we build the COMPONENT_REF of a formerly volatile local off the FRAME decl we have to make sure to mark the COMPONENT_REF as TREE_THIS_VOLATILE. While the GIMPLE operand scanner looks at the FIELD_DECL this is not how volatile GENERIC refs work. 2021-08-09 Richard Biener <[email protected]> PR middle-end/101824 * tree-nested.c (get_frame_field): Mark the COMPONENT_REF as volatile in case the variable was. * gcc.dg/tree-ssa/pr101824.c: New testcase.
