Miss Islington (bot)	5535482d2a	[3.14] gh-136541: Fix several problems of perf trampolines in x86_64 and aarch64 (GH-136500) (#136544 ) gh-136541: Fix several problems of perf trampolines in x86_64 and aarch64 (GH-136500) This commit fixes the following problems: * The x86_64 trampolines are not preserving frame pointers * The hardcoded offsets to the code segment from the FDE only worked properly for x64_64 * The CIE data was not following conventions of aarch64 * The eh_frame for aarch64 was not fully correct (cherry picked from commit `236f733d8f`) Co-authored-by: Pablo Galindo Salgado <Pablogsal@gmail.com>	2025-07-11 14:06:19 +00:00
