Subject: [PATCH v2 2/5] sim: Make WITH_{TRACE,PROFILE}-based macros bool
Date: Sun, 25 Sep 2022 08:42:03 +0000	[thread overview]
Message-ID: <5e4eb547bed6f4335099f242aebd39768bb1cb40.1664095312.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1664095312.git.research_trasio@irq.a4lg.com>

Clang generates a warning if there is an ambiguous expression (possibly a
bitwise operation (& or |), but a logical operator (&& or ||) is used;
"-Wconstant-logical-operand").  On the default configuration, it causes a
build failure (unless "--disable-werror" is specified).

This is caused by predicate macros that use the form (base_variable & flag).
Clang considers them as regular integer values (not boolean) and
generates that warning.

This commit makes Clang think those predicate macros to be boolean.

sim/ChangeLog:

	* common/sim-profile.h (WITH_PROFILE_INSN_P,
	WITH_PROFILE_MEMORY_P, WITH_PROFILE_MODEL_P,
	WITH_PROFILE_SCACHE_P, WITH_PROFILE_PC_P, WITH_PROFILE_CORE_P):
	Make predicate macros boolean.
	* common/sim-trace.h (WITH_TRACE_P, WITH_TRACE_ANY_P): Likewise.
