Hi,
This patch improves register pressure scheduling (both SCHED_PRESSURE_WEIGHTED
and SCHED_PRESSURE_MODEL) to better estimate number of available registers.
At the moment the scheduler does not account for spills in the prologues and
restores in the epilogue, which occur from use of call-used
Hi Jakub,
Thanks for your feedback! See below.

Hello.
I added missing gimple_asm_string comparison for a function with an asm
statement.
Bootstrap and regression tests still running, ready for trunk after it finishes?
Thank you,

Hello,
This patch sets SECTION_EXCLUDE flag for LTO sections in lhd_begin_section and
fixes the corresponding gcc_GAS_CHECK_FEATURE.
Approved here: https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01535.html
Bootstrapped and regtested on i686-linux and x86_64-linux, committed to trunk.

Hello!
The fix that fixed scheduler issues with AND addresses (the fix
prevented early exit for MEM_READONLY_P addresses when AND alignment
addresses were involved) caused some fall-out for libgo testsuite.
These tests triggered an assert in mems_in_disjoint_alias_sets_p,
which checks for zero ali
Hello,
looking though the patterns on the branch (not specifically the ones
attached here), I am surprised to see so few calls to has_single_use. In
RTL-land, we don't even valueize if there are several uses, so the
question doesn't occur. In generic, we assume everything is single use

It turned out that there is another spot where we need to allow

Hmm, the patch is somewhat ugly and I do not know why MingW32 defines mkdir
macro and how. If Kai Tietz or other MingW32 maintainer is OK about it, the
patch is OK.
