Even with this patch, on amd64, there is still another issue, where a few negative numbers are left-shifted: /usr/work/share/dim/ports/lang/go/work/go/src/cmd/6c/txt.c:995:28: error: shifting a negative signed value is undefined [-Werror,-Wshift-negative-value] f->vconst |= (vlong)~0 << 32; ~~~~~~~~~ ^ For this, I propose the next patch, for src/cmd/6c/txt.c, which just casts the constant to uvlong. This should result in no functional change, but I am unsure how to run any go test suite to verify. Alternatively, the makefile(s) can be changed to squelch the warning, if you like that better. -- You are receiving this mail because: You are the assignee for the bug.
