rockbox/firmware/asm/asm.make, branch master My Rockbox tree Apparently make doesn't like inline comments 2012-03-28T21:14:39+00:00 Thomas Martitz kugel@rockbox.org 2012-03-28T21:14:39+00:00 a54c687300a53f2c6d6dab4b512ffa15c0ccce45 Change-Id: If604af9713cf95dafbeb1a601219ca1b3a8964fa

build system: completely autodetect target cpu architecture. 2012-03-28T21:02:39+00:00 Thomas Martitz kugel@rockbox.org 2012-03-28T20:57:13+00:00 7b1a369cf7801f98139189ade463f3a460f78d85 The existing ARCH Makefile variable is exported to the C code as well. Additionally the version (arm-only for now) is detected as well. This allows to for complete autodetection, i.e. that optimized ASM is picked up if determined by preprocessor (CPU_ARM, etc). Building a sim/raaa on a arm host will now automatically generate a arm optmized build like we have for native targets. Change-Id: I0b35393f8fb3ebd20beaa9e7371fa57bf3782107

Add framework to let make automatically pick optimized asm implementations over generic C ones to firmware. 2012-01-22T17:46:45+00:00 Thomas Martitz kugel@rockbox.org 2012-01-07T18:49:02+00:00 8e8e978de6b6283b66a6829fa8c5e3b94674ce7d Example: for a file asm/foo.c, make will look for asm/arm/foo.[cS] and compile it if found. If not found it'll fall back to asm/foo.c. Also introduce new ARCH make variable. This is automatically detected by configure. It is distinct from CPU since CPU defines the dir used for the target tree (i.e. firmware/target/X, so it can be "hosted"). ARCH really has the target isa and can be x86 for sims/raaa too.
