Subject: [Bug target/113312] Update __attribute__((interrupt)) for Intel FRED
Date: Fri, 12 Jan 2024 01:00:56 +0000	[thread overview]
Message-ID: <bug-113312-4-h2WuQn4mXK@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-113312-4@http.gcc.gnu.org/bugzilla/>

--- Comment #14 from H.J. Lu <hjl.tools at gmail dot com> ---
Here is a branch for __attribute__((no_callee_saved_registers)):

https://gitlab.com/x86-gcc/gcc/-/commits/users/hjl/pr113312/master

Calling a function with __attribute__((no_callee_saved_registers))
doesn't work since GCC won't restore clobbered caller-saved registers.
Also calling a function with __attribute__((no_callee_saved_registers))
via a function pointer won't work correctly.
