Cover letter [PATCH 0/7] Cleanup and document tuning files
This is a documentation and cleanup of the tuning files. Every tuning listed in AVAILTUNES was built for core-image-minimal! The following is a list of failure conditions with explanations:
ep9312 - binutils - gas fails to recognize -march=ep9312 as valid
(see binutils armv5e note below)
cortexm3 - gcc reports the target CPU does not support ARM mode cortexr4 - gcc reports the target CPU does not support ARM mode
mips64* - These are not yet supported by the OE compilers
(SH is new and experimental, based on the existing tunings) sh3* - These are missing a patch in the compiler:
sh3-installfix-fixheaders.patch
sh*eb - Big endian varieties are defined, but not supported
x32 ABI variants for core2-64 and x86-64 - needs x32 layer
Multilibs verified to work:
x86-64 & x86
ppce5500 & ppc64e5500
---
Note armv5e & binutils-gas:
Finally there is a small patch to binutils gas that adds armv5e as a valid architecture, otherwise all of the armv5e* tunings fail, even though gcc says they are valid architectures.
---
Future work:
I'm still not completely happy with the ARM tunings, but it's too disruptive to change them at this time. I'd like to move to something closer to how MIPS is configured. Define various "variants" for the various tunings, instead of simply defining the ARMPKGARCH. The current method prevents us from having a single build that can build packages optimized for armv5te and armv7a. While this is not likely to be a huge problem for the time being, it may lead to problems for feed based systems that can support multiple ARM architecture families.
The following changes since commit 38ee88e3b32b7444d7f1eb64f1b4f69a48fe0458:
gdb: build with expat, add missing RRECOMMENDS_gdbserver (2012-04-03 14:10:44 +0100)
