Subject: Re: [PATCH 0/4] gas: Add support for LLVM addrsig and addrsig_sym.
Date: Wed, 25 May 2022 15:46:26 +0900	[thread overview]
Message-ID: <CANqewP0DQeW6K=zMuhgKNh6yyY_zD5R_NJn44rozt_X6aUdVMg@mail.gmail.com> (raw)

Oops, I forgot to add a newline after the subject and the mailer ate the body.
Here is the full description:
---
LLVM's addrsig extension [1] allows the compiler to pass on information
about whether a symbol's address is taken to the linker, which in turns
use this info to perform (safe) Identical Code Folding optimization at
link-time.

This patch adds support for the relevant LLVM assembler directives,
which is a prerequisite for GCC support of the feature.
