clang warnings with LTO
gcc 11.2.1
Looks like no one have been trying to compile clang using gcc and optimise it
using LTO. Just done that and LTO reported 550 [-Wmaybe-uninitialized] warnings
Summary stats of all warnings:
[tkloczko@barrel SPECS]$ cat clang.out | grep -- -W | sed 's/.*\[//; s/\]//' |
sort | uniq -c | sort -nr
550 -Wmaybe-uninitialized
13 -Wuninitialized
3 -Wfree-nonheap-object
1 -Walloc-size-larger-than=
Full log of all warnings is in attachment.</pre>
