Changes in V3: - Rebased to linux-perf-tools branch. - Squash symbol-elf.c and symbol.h into same commit. - In map.c, merge dso__is_pie() call into existing if statement. - In arm-cs-trace-disasm.py, remove debug artifacts.
Changes in V2: - In dso__is_pie() (symbol-elf.c), Decrease indentation, add null pointer checks per Leo Yan review. - Updated mailing list distribution
Fedora 37 distributed shared binary and executable mapped files show a zero text section offset. Starting with the Fedora 38 distribution, the shared binary and executable mapped files show a non-zero text section offset for some binaries. The text offset parameter is never passed into the arm-cs-trace-disasm.py script to allow the script to adjust the start/end address range passed to objdump. This adjustment is required to correctly offset into the dso text section. Not doing so results in an incorrect user instruction trace display for Fedora 38 (and later) user trace output.
Steve Clevenger (4): Add dso__is_pie call to identify ELF PIE Force MAPPING_TYPE__IDENTIY for PIE Add map pgoff to python dictionary based on MAPPING_TYPE Adjust objdump start/end range per map pgoff parameter
