You are probably using a console that has quite small column limit, so that you see it automatically wrapped. I see: ... -flimit-function-alignment This option lacks documentation. -flive-patching Same as -flive-patching=. Use the latter option instead. -flive-patching=[inline-only-static|inline-clone] Control IPA optimizations to provide a safe compilation for live-patching. At the same time, provides multiple-level control on the enabled IPA optimizations. ^--- the long line -flive-range-shrinkage Relief of register pressure through live range shrinkage. -floop-block Enable loop nest transforms. Same as -floop-nest-optimize.

I see it: === ERROR type #3: dot, space, space, new sentence (3 error(s)) === gcc/common.opt:2190:62:optimizations to provide a safe compilation for live-patching.█At the same gcc/doc/invoke.texi:9291:14:optimizations.█For example, inlining a function into its caller, cloning gcc/doc/invoke.texi:9297:37:impacted functions for each function.█In order to control the number of > but I didn’t see spaces + tabs mix issue with the script. could you please > specify? This is a new check that I've just installed: === ERROR type #1: a space should not precede a tab (1 error(s)) === gcc/opts.c:2350:0: ████████control_optimizations_for_live_patching (opts, opts_set, Martin > > thanks. > > Qing > * > * >
