But the "m" asm constraint # doesn't enforce that. # # That can lead to build errors if the compiler chooses a non-aligned # displacement, as seen with GCC 14: # # /tmp/ccuSzwiR.s: Assembler messages: # /tmp/ccuSzwiR.s:2579: Error: operand out of domain (39 is not a multiple of 4) # make[5]: *** [scripts/Makefile.build:229: net/core/page_pool.o] Error 1 # # Dumping the generated assembler shows: # # ld 8,39(8) # MEM[(const struct atomic64_t )_29].counter, t # # Use the YZ constraints to tell the compiler either to generate a DS-form # displacement, or use an X-form instruction, either of which prevents the # build error. # # See commit 2d43cc701b96 ("powerpc/uaccess: Fix build errors seen with # GCC 13/14") for more details on the constraint letters. # # Fixes: 9f0cbea0d8cc ("[POWERPC] Implement atomic{, 64}_{read, write}() without volatile") #
