Subject: [PATCH 1/1] gdb, testsuite: Adapt gdb.base/callfuncs.exp for new clang warnings.
Date: Wed, 8 Jun 2022 09:17:17 +0200 [thread overview]
Message-ID: <20220608071717.3953324-1-felix.willgerodt@intel.com> (raw)
This patch fixes two issues with callfuncs.exp, which are both related
to new Clang warnings:
1) Clang 15.0.0 added a new warning for deprecated non-prototype functions:
https://reviews.llvm.org/D122895
Callfuncs.exp is impacted and won't run due to new warnings:
callfuncs.c:339:5: warning: a function declaration without a prototype is
deprecated in all versions of C and is not supported in C2x
[-Wdeprecated-non-prototype]
int t_float_values (float_arg1, float_arg2)
This patch disables those warnings with -Wno-deprecated-non-prototype.
Removing the test for deprecated syntax would also be an option. But I will
leave that for others to decide.
2) The other new warnings are about comparing a define with floats and doubles:
callfuncs.c:518:1: warning: floating-point comparison is always true; constant
cannot be represented exactly in type 'float' [-Wliteral-range]
DEF_FUNC_VALUES_3(fc, float, crealf, cimagf)
This can be fixed by making the define a float.
