Subject: [PATCH 0/4] Add CET IBT Support to MUSL
Indirect Branch Tracking is an X86 feature which enforces that
indirect-branches to always target an endbranch instruction, confing the
execution flow of applications and protecting against control-flow hijacking
attacks. This patch series adds IBT support to MUSL.
Signed-off-by: Joao Moreira <joao.moreira@...el.com>
Joao Moreira (4):
Support ASFLAGS in configure and Makefile
Add ENDBRANCH64 and ENDBRANCH32 macro definitions
Add endbr64 to x86_64 assembly functions
Add endbr32 to i386 assembly functions
