--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:f1125cf88ac0c97d819e4f81d556fbcd1161270e commit r9-8391-gf1125cf88ac0c97d819e4f81d556fbcd1161270e Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Mar 11 18:35:13 2020 +0100 pdp11: Fix handling of common (local and global) vars [PR94134] As mentioned in the PR, the generic code decides to put the a variable into lcomm_section, which is a NOSWITCH section and thus the generic code doesn't switch into a particular section before using ASM_OUTPUT{_ALIGNED{,_DECL}_}_LOCAL, on many targets that results just in .lcomm (or for non-local .comm) directives which don't need a switch to some section, other targets put switch_to_section (bss_section) at the start of that macro. pdp11 doesn't do that (and doesn't have bss_section), and so emits the lcomm/comm variables in whatever section is current (it has only .text/.data and for DEC assembler rodata). The following patch fixes that by putting it always into data section, and additionally avoids emitting an empty line in the assembly for the lcomm vars. 2020-03-11 Jakub Jelinek <ja...@redhat.com> PR target/94134 * config/pdp11/pdp11.c (pdp11_asm_output_var): Call switch_to_section at the start to switch to data section. Don't print extra newline if .globl directive has not been emitted. * gcc.c-torture/execute/pr94134.c: New test.
