Subject: [PATCH 06/12] selftests: lib.mk: Add rule to build object file from C source file
Date: Mon, 14 Jan 2019 14:51:38 +0100	[thread overview]
Message-ID: <20190114135144.26096-7-geert+renesas@glider.be> (raw)
Message-ID: <20190114135138.Q9Ls61Ogsn-kEFVuEZ10yr33ZqRBhEBlTT9utleUH5g@z> (raw)
In-Reply-To: <20190114135144.26096-1-geert+renesas@glider.be>

Currently there are rules to compile and link one or more C or
assembler source files into a full executable, and to assemble a single
assembler source into an object file.

Add a generic rule to compile a single C source file into an object
file, for reuse of object files in multiple executables.
