>From 96d1a2e5cb7bc92c89fdcc370b2e1ef977d814cf Mon Sep 17 00:00:00 2001 From: cqwrteur <[email protected]> Date: Sat, 25 Apr 2026 14:23:32 +0800 Subject: [compiler-rt][sanitizer] Remove linux/scc.h (#194116) #194110 Linux Kernel has removed scc.h header completely from the source code Therefore, we need to remove the usage in compiler-rt/sanitizer too. https://github.com/torvalds/linux/commit/64edfa65062dc4509ba75978116b2f6d392346f5#diff-1ca78e598a5041ee51ae795d168435afad598b82a7a0ce80f215993589b96c7c Without removing it, not only it breaks compiler-rt but also GCC build since GCC always builds libsanitizer for linux targets. After merging this we will need to cherry pick to GCC.
