2024-06-26perf util: Make util its own libraryIan Rogers1-1/+1
Make the util directory into its own library. This is done to avoid compiling code twice, once for the perf tool and once for the perf python module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.c are made part of this library.

2019-02-14perf tools: Rename build libperf to perfJiri Olsa1-1/+1
Rename build libperf to perf, because it's used to build perf. The libperf build object name will be used for libperf library.

2015-09-01perf dwarf: Fix potential array out of bounds accessWang Nan1-1/+1
There is a problem in the dwarf-regs.c files for sh, sparc and x86 where it is possible to make an out-of-bounds array access when searching for register names. This patch fixes it by replacing '<=' to '<', so when register (number == XXX_MAX_REGS), get_arch_regstr() will return NULL.

2013-03-15perf tools: Fix build on non-glibc systems due to libio.h absenceCody P Schafer1-1/+1
Including libio.h causes build failures on uClibc systems (which lack libio.h). It appears that libio.h was only included to pull in a definition for NULL, so it has been replaced by stddef.h. On powerpc, libio.h was conditionally included, but could be removed completely as it is unneeded. Also, the included of stdlib.h was changed to stddef.h (as again, only NULL is needed).
