Subject: [PATCH v2 0/8] Turn some C warnings into errors by default
Date: Tue, 14 Nov 2023 18:50:11 +0100 [thread overview]
Message-ID: <cover.1699983736.git.fweimer@redhat.com> (raw)
This new series covers:
-Wint-conversion
-Wimplicit-function-declaration
-Wimplicit-int
-Wreturn-mismatch
-Wincompatible-pointer-types
-Wdeclaration-missing-parameter-type (new)
There are now gcc.dg/permerror-*.c tests which track the graduation of
warnings to errors.
It turns out that pedpermerror was indeed unnecessary, and I can use
permerror_opt directly (or DK_PERMERROR in case I call one of the
low-level functions).
While working on this I found out that -Wimplicit-int is mostly
ineffective in system headers, so I fixed that for consistency. I also
added a new -Wdeclaration-missing-parameter-type warning because missing
types in parameter lists in function declarations (as opposed to
old-style function definitions) are not covered by -Wimplicit-int, and
probably shouldn't be because the omitted types are not necessarily int.
This still depends on a couple of unreviewed patches. In particular, I
do not want to break the AArch64 bootstrap, so the first patch looks
like a blocker.
[PATCH] aarch64: Avoid -Wincompatible-pointer-types warning in Linux unwinder
<https://inbox.sourceware.org/gcc-patches/874jht5tsq.fsf@oldenburg.str.redhat.com/>
[PATCH] aarch64: Call named function in gcc.target/aarch64/aapcs64/ice_1.c
<https://inbox.sourceware.org/gcc-patches/87r0kx6eez.fsf@oldenburg.str.redhat.com/>
[PATCH] gm2: Add missing declaration of m2pim_M2RTS_Terminate to test
<https://inbox.sourceware.org/gcc-patches/874jhp3nwf.fsf@oldenburg.str.redhat.com/>
Thanks,
Florian
Florian Weimer (8):
Add tests for validating future C permerrors
c: Turn int-conversion warnings into permerrors
c: Turn -Wimplicit-function-declaration into a permerror
c: Turn -Wimplicit-int into a permerror
c: Do not ignore some forms of -Wimplicit-int in system headers
c: Turn -Wreturn-mismatch into a permerror
c: Turn -Wincompatible-pointer-types into a permerror
c: Add new -Wdeclaration-missing-parameter-type permerror
