Replace yasm with nasm as yasm is no longer maintained and has unpatched CVEs (CVE-2024-45534, CVE-2024-45535). Nasm is actively maintained and generates compatible listing files. The patch includes: - Changed assembler invocation from yasm to nasm - Removed unsupported -L nasm parameter - Added dual-format parser for org directives (yasm and nasm syntax) - Implemented 1:1 line mapping fallback for nasm listing format - Updated documentation Both test cases (loop-tnt.ptt and dump-all-packets.ptt) now pass on target system. Upstream-Status: Submitted [intel/libipt#120] Signed-off-by: Yogesh Tyagi <yogesh.tyagi@intel.com>

Replace yasm with nasm as the default assembler for pttc. Yasm is no longer actively maintained and has known security vulnerabilities, while nasm is actively developed and provides equivalent functionality. Key changes: 1. Update assembler invocation from 'yasm' to 'nasm' 2. Remove '-L nasm' option (nasm doesn't need this flag) 3. Adjust argv array indices after removing the flag 4. Support both yasm and nasm org directive formats: - yasm: [org 0x100000] - nasm: org 0x100000 5. Handle nasm's listing format which lacks %line directives by implementing 1:1 line mapping fallback for source correlation The changes maintain backward compatibility with existing .ptt test files while enabling nasm as the preferred assembler. Tested with: - test/src/loop-tnt.ptt - test/src/dump-all-packets.ptt Both tests generate valid PT traces that can be decoded with ptdump. Signed-off-by: Yogesh Tyagi <yogesh.tyagi@intel.com>

Thanks for your patch. Using nasm is a good idea.
How about the other tests? |
