-Subject: [PATCH] linux/arm/raw_syscall.h: avoid r7 specified register
- variables with Thumb
-
-If Thumb code is being generated and frame pointers are enabled, the
-Thumb frame pointer in r7 clashes with any local variable which may
-need to be assigned to r7 (e.g. the syscall NR when making a raw
-syscall).
-
-With gcc, the double use of r7 results in a build error, e.g.
-
-  strace-4.22/tests/inject-nf.c:86:1: error: r7 cannot be used in asm here
-
-With clang, the double use of r7 can result in the compiler silently
-generating broken code which crashes at run time due to frame pointer
-corruption:
-
-  https://bugs.llvm.org/show_bug.cgi?id=34165
-
-In most cases the problem isn't visible as frame pointers will be
-disabled automatically due to optimisation level. However to handle
-cases where frame pointers are enabled (e.g. when CFLAGS etc are set
-to support a debug build, etc) provide a version of raw_syscall_0
-which manually saves and restores the frame pointer value in r7
-to a temporary register before setting up the syscall NR in r7
-and invoking the syscall.
-
-* linux/arm/raw_syscall.h (raw_syscall_0) [__thumb__]: Provide
-an alternative version.
-
-Upstream-Status: Backport
