Details:
- Validate and bug fix for linaro binary toolchain 2012.04 release.
- Investigate code size regressions in 4.7
Find more regression cases due to loop invariant hoisting, and tests should we can reduce some codesize with option -fno-move-loop-invariants. Some regressions are due to pass_reorder_blocks, which is disabled for -Os in 4.7. For some cases, ivopt will introduce to more codes and function inline might lead to more spilling. We also try linaro 2012.04 baremetal build. But there is a few bytes regression compared with 4.7 trunk. 3. Setup the qemu env following Michael’s instructions (https://wiki.linaro.org/MichaelHope/Sandbox/QEMUCrossTest) and tests show it work. 4. Try to build gcc-linaro-2012.04 configured with "--with-fpu=neon --with-float=hard" based on a precise sysroot (precise-sysroot-armhf-r0.tar.bz2) from http://people.linaro.org/~michaelh/incoming * Linux build is OK without any change. * Mingw32 build reports error. After removing the code, the build PASS. [ERROR] .../libc/usr/include/arm-linux-gnueabihf/sys/types.h:117:19: error: two or more data types in declaration specifiers
See the oneiric sysroot patch. This needs to be brought forward for Precise on mingw.
