Hi Richard,
Your patch a076632e274abe344ca7648b7c7f299273d4cbe0 appears to have broken bootstrap-O3 for 32-bit armhf. Do you have an AArch32-capable machine to reproduce/investigate this on? Let me know if not, and I'll make a proper bug report with a testcase.

This rips out the code which was added for Java and should have been an assertion when we didn't have debug stmts. To not regress g++.dg/tree-ssa/array-temp1.C we have to adjust the testcase to not look for a no longer applied invalid optimization. 2021-05-10 Richard Biener <rguenther@suse.de> PR middle-end/100464 PR c++/100468 gcc/ • gimple-fold.c (canonicalize_constructor_val): Do not set TREE_ADDRESSABLE. gcc/cp/ • call.c (set_up_extended_ref_temp): Mark the temporary addressable if the TARGET_EXPR was. gcc/testsuite/ • gcc.dg/pr100464.c: New testcase. • g++.dg/tree-ssa/array-temp1.C: Adjust. </cut> Details: https://ci.linaro.org/job/tcwg_gcc-bisect-gnu-master-arm-bootstrap_O3/16/artifact/artifacts/jenkins/mail-body.txt/*view*/ Even more details: https://ci.linaro.org/job/tcwg_gcc-bisect-gnu-master-arm-bootstrap_O3/16/artifact/artifacts/ This message was sent by Atlassian Jira (v8.11.1#811002-sha1:94cd716) Jira is improving email notifications, share your feedback!
