Subject: [Buildroot] [PATCH] cut down on implicit rule searches
Date: Wed, 7 Oct 2009 23:18:21 +0200 [thread overview]
Message-ID: <20091007211821.GJ23847@mx.loc> (raw)
Hi,
The subject says it all, info make explains it in detail.
Please install.
PS: obviously reduces the amount of time make wastes trying to
match pattern rules which we don't have nor need.
PPS:
`-r'
`--no-builtin-rules'
Eliminate use of the built-in implicit rules (*note Using Implicit
Rules: Implicit Rules.). You can still define your own by writing
pattern rules (*note Defining and Redefining Pattern Rules:
Pattern Rules.). The `-r' option also clears out the default list
of suffixes for suffix rules (*note Old-Fashioned Suffix Rules:
Suffix Rules.). But you can still define your own suffixes with a
rule for `.SUFFIXES', and then define your own suffix rules. Note
that only _rules_ are affected by the `-r' option; default
variables remain in effect (*note Variables Used by Implicit
Rules: Implicit Variables.); see the `-R' option below.
PPPS: (excerpt only for _one_ attempted match that is avoided with that patch)
