2013-05-02Follow-on patch to r197595 to complete the replacement of truncating divides ↵Teresa Johnson7-38/+40
in... Follow-on patch to r197595 to complete the replacement of truncating divides in profile scaling code with rounding divide equivalents using helper routines in basic-block.h. In addition to bootstrap and profiledbootstrap builds and tests (with and without LTO), I built and tested performance of the SPEC cpu2006 benchmarks with FDO on a Nehalem system. I didn't see any performance changes that looked significant. 2013-05-02 Teresa Johnson <tejohnson@google.com> * loop-unswitch.c (unswitch_loop): Use helper routines with rounding divides. * cfg.c (update_bb_profile_for_threading): Ditto. * tree-inline.c (copy_bb): Ditto.

2013-04-30gcc: arm: linux-eabi: fix handling of armv4 bx fixups when linkingMike Frysinger3-3/+14
The bpabi.h header already sets up defines to automatically use the --fix-v4bx flag with the assembler & linker as needed, and creates a default assembly & linker spec which uses those. Unfortunately, the linux-eabi.h header clobbers the LINK_SPEC define and doesn't include the v4bx define when setting up its own. So while the assembler spec is retained and works fine to generate the right relocs, building for armv4 targets doesn't invoke the linker correctly so all the relocs get processed as if we had an armv4t target. You can see this with -dumpspecs when configuring gcc for an armv4 target and using --with-arch=armv4: $ armv4l-unknown-linux-gnueabi-gcc -dumpspecs |& grep -B 1 fix-v4bx *subtarget_extra_asm_spec: .... %{mcpu=arm8|mcpu=arm810|mcpu=strongarm*|march=armv4|mcpu=fa526|mcpu=fa626:--fix-v4bx} ... With this fix in place, we also get the link spec: $ armv4l-unknown-linux-gnueabi-gcc -dumpspecs |& grep -B 1 fix-v4bx *link: ... %{mcpu=arm8|mcpu=arm810|mcpu=strongarm*|march=armv4|mcpu=fa526|mcpu=fa626:--fix-v4bx} ... And all my hello world tests / glibc builds automatically turn the bx insn into the 'mov pc, lr' insn and all is right in the world.

2013-04-29This patch fixes PR bootstrap/57077.Teresa Johnson7-22/+46
This patch fixes PR bootstrap/57077. Certain new uses of apply_probability are actually scaling the counts up, and the scale factor should not be treated as a probability as the value may exceed REG_BR_PROB_BASE. One example (from the PR) is when scaling counts up in LTO when merging profiles. Another example I found when preparing the patch to use the rounding divide in more places is when inlining COMDAT functions. Add new helper function apply_scale that does the scaling without the probability range check. I audited the new uses of apply_probability and changed the calls as appropriate. 2013-04-29 Teresa Johnson <tejohnson@google.com> PR bootstrap/57077 * basic-block.h (apply_scale): New function.
