Hi! My linux-next builds for Fedora[1] since yesterday fail with the following error: > In file included from <command-line>: > ./include/crypto/sha256_base.h: In function ‘lib_sha256_base_do_update.constprop.isra’: > ././include/linux/compiler_types.h:332:20: error: invalid 'asm': operand is not a condition code, invalid operand code 'c' > 332 | #define asm_inline asm __inline > | ^~~ See below for the full error message[2]. This happens on Fedora rawhide and 38 (both use gcc13), but not on Fedora 37 (which uses gcc12). Is this known already or do I have to bisect this?
