--- Comment #8 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- Author: rsandifo Date: Tue Jan 15 16:46:54 2019 New Revision: 267941 URL: https://gcc.gnu.org/viewcvs?rev=267941&root=gcc&view=rev Log: PR inline-asm/52813 revisited The original patch for this PR made it an error to list the stack pointer in the clobber list of an inline asm. However, the general feeling seemed to be that going straight to a hard error was too harsh, since there's quite a bit of existing code that has the clobber. This patch implements the compromise discussed on IRC of making it a -Wdeprecated warning instead. 2019-01-15 Richard Sandiford <richard.sandif...@arm.com> gcc/ PR inline-asm/52813 * doc/extend.texi: Document that listing the stack pointer in the clobber list of an asm is a deprecated feature. * common.opt (Wdeprecated): Moved from c-family/c.opt. * cfgexpand.c (asm_clobber_reg_is_valid): Issue a -Wdeprecated warning instead of an error for clobbers of the stack pointer. Add a note explaining why. gcc/c-family/ PR inline-asm/52813 * c.opt (Wdeprecated): Move documentation and variable to common.opt. gcc/d/ PR inline-asm/52813 * lang.opt (Wdeprecated): Reference common.opt instead of c.opt. gcc/testsuite/ PR inline-asm/52813 * gcc.target/i386/pr52813.c (test1): Turn the diagnostic into a -Wdeprecated warning and expect a following note:.
