Subject: [PATCH v4 2/2] x86: Add general_regs_only function attribute
Date: Wed, 14 Apr 2021 15:39:18 -0700 [thread overview]
Message-ID: <20210414223918.230495-3-hjl.tools@gmail.com> (raw)
In-Reply-To: <20210414223918.230495-1-hjl.tools@gmail.com>
commit 87c753ac241f25d222d46ba1ac66ceba89d6a200
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri Aug 21 09:42:49 2020 -0700
x86: Add target("general-regs-only") function attribute
is incomplete since it is impossible to call integer intrinsics from
a function with general-regs-only target attribute.
1. Add general_regs_only function attribute to inform the compiler that
functions use only general purpose registers. When making inlining
decisions on such functions, non-GPR compiler options are excluded.
2. Add general_regs_only attribute to x86 intrinsics which use only
general purpose registers.
