Bug #: 52646
Summary: Clang LLVM's __attribute__((naked)) for GCC when
compiling for x86
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: th020...@gmail.com
It would be helpful to system developers if GCC had something similar to Clang
LLVM's __attribute__((naked)) for x86 targets. There are cases, such as when
interfacing with assembly or when handling an interrupt, when the code that
precedes and follows a normal function causes problems.
GCC already has __attribute__((interrupt)) for multiple targets, but doesn't
implement it for x86. Personally, if the feature were to be implemented, I
believe naked is more explicit.
I'd be glad to do this myself, but I'm not acquainted with GCC at all. What
files should I look in to get started?
