[Bug target/83143] [SH]: Assembler messages: invalid operands (*UND* and .text sections) for `-'
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83143 --- Comment #16 from Giulio Benetti --- Thank you. Yes I've just tested "-freorder-blocks-algorithm=simple" solution of gcc 9.x and 11.x with -Os enabled and it works perfectly. By the way, is it useful for you if I provide .i and .s file with -save-temps?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83143 --- Comment #15 from John Paul Adrian Glaubitz --- (In reply to Giulio Benetti from comment #14) > This bug still shows up in gcc version 9.x and 11.x. But not on version 10.x > I've found the simple work-around to disable the optimization(override > CFLAGS with -O0) and it works. That removes too many optimizations. As explained in comment 5 [1], it should be enough to add "-freorder-blocks-algorithm=simple" instead of just removing all optimizations. > [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83143#c5

AFAIR it's -ml -m4 -matomic-model=soft-gusa

This is a reduced version of the original reproduction. Creduce will happily make it even smaller if you let it do crazy enum-to-pointer casts and various other warning-inducing things, but this builds with -Wall -Werror.

So I guess this is where the error comes from. But no idea why the label is not there. AFAIR Segher did some stuff for block reordering. Maybe he's got any clue.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83143 --- Comment #5 from John Paul Adrian Glaubitz --- It's fixed by adding "-freorder-blocks-algorithm=simple" which overrides "-freorder-blocks-algorithm=stc" from "-O2".
