[PATCH] Fix type warnings from clang compiler.
- From: Chih-Hung Hsieh <chh at google dot com>
- To: elfutils-devel at lists dot fedorahosted dot org
- Date: Fri, 04 Sep 2015 12:04:11 -0700
- Subject: [PATCH] Fix type warnings from clang compiler.
* Replace K&R function definition with prototypes to match their declarations.
Clang gives errors of: promoted type 'int' of K&R function parameter is not compatible with the parameter type
* Add const declaration to locs, which was passed a const.
Clang gives errors of: passing 'const Elf_Data *' to parameter of type 'Elf_Data *' discards qualifiers
* Avoid clang errors of: comparison of nonnull parameter ... equal to a null pointer is false
on first encounter [-Werror,-Wtautological-pointer-compare]
The parameter was declared as non-null.
* Replace abs with labs for int64 values.
* Remove unused static variables.
* Init local variable before use, where static analysis failed.
