2024-04-02Fix up duplicated words mostly in comments, part 1Jakub Jelinek1-1/+1
Like in r12-7519-g027e30414492d50feb2854aff38227b14300dc4b, I've done git grep -v 'long long\|optab optab\|template template\|double double' | grep ' \([a-zA-Z]\+\) \1 ' This is just part of the changes, mostly for non-gcc directories. I'll try to get to the rest soon. Obviously, the above command also finds cases which are correct as is and shouldn't be changed, so one needs to manually inspect everything. I'd hope most of it is pretty obvious, but the config/ and libstdc++-v3/ hunks include a tweak in a license wording, though other copies of the similar license have the wording right. 2024-04-02 Jakub Jelinek <jakub@redhat.com> * Makefile.tpl: Fix duplicated words; returns returns -> returns. config/ * lcmessage.m4: Fix duplicated words; can can -> can, package package -> package. libdecnumber/ * decCommon.c (decFinalize): Fix duplicated words in comment; the the -> the. libgcc/ * unwind-dw2-fde.c (struct fde_accumulator): Fix duplicated words in comment; is is -> is. libgfortran/ * configure.host: Fix duplicated words; the the -> the. libgm2/ * configure.host: Fix duplicated words; the the -> the. libgomp/ * libgomp.texi (OpenMP 5.2): Fix duplicated words; with with -> with.

2016-11-04libiberty: Fix -Wimplicit-fallthrough warnings.Mark Wielaard1-2/+6
Adjust some comments, add some explicit fall through comments or explicit returns where necessary to not get implicit-fallthrough warnings. All fall throughs were deliberate. In one case I added an explicit return false for clarity instead of falling through a default case (that also would return false). libiberty/ChangeLog: * cplus-dem.c (demangle_signature): Move fall through comment. (demangle_fund_type): Add fall through comment between 'G' and 'I'. * hashtab.c (iterative_hash): Add fall through comments. * regex.c (regex_compile): Add Fall through comment after '+'/'?'.
