https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267401 Bug ID: 267401 Summary: clang; i386 ; generates code for target that doesn't support it (CET instructions) Product: Base System Version: Unspecified Hardware: i386 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: martin@bxlr.sk CPU target: i586, clang generates code that is not supported by target causing program to crash due to illegal instruction. Illegal instruction is: endbr32 Tested on physical box running i386 FreeBSD 13.1. CPU: Pentium/P55C (233.87-MHz 586-class CPU) Origin="GenuineIntel" Id=0x543 Family=0x5 Model=0x4 Stepping=3 Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,MMX> Simple "hello world" c code compiled with CFLAGS=-g -march=i586 -fcf-protection. As target doesn't support flow control -fcf-protection should not be used.
