      S390: Makefile + Build Toolchain Updates · 1091c2f0
      joransiu authored 
      This is the first of several commits to contribute Linux on z Systems
(s390/s390x) port of V8.  We will be breaking up the changes into several
(hopefully) logical commits.

This commit contains the changes to V8 Makefile and build toolchains to
introduce S390 macros and compiler options.  Just for awareness for reviewers
is that s390 is 31-bit (not 32!) big-endian platform on Linux on z.  (MSB of address
is used to distinguish between 24-bit vs 31-bit addressing!)  s390x is
64-bit Linux on z.  Names follow the general linux convention on the platform.

A quick roadmap on upcoming commits:
- Add \#include of S390 header files in common files
- S390 related tests + tooling changes
- printf macro for printing size_t values.
- S390 platform-specific code generation code (bulk of changes!)

      Re-enable LLVM LTO for ARM. · fef4fab6
      pcc authored 
      v8 is optimized for speed. Because GCC LTO merges flags at link time,
we disable LTO to prevent any -O2 flags from taking precedence over v8's
-Os flag. However, LLVM LTO does not work this way so we keep LTO enabled
under LLVM.

This fixes the ARM build in the cfi_vptr==1 configuration, which requires
LLVM LTO.

      PPC: Changes to allow AIX to compile with gcc 4.8.3 · 86852190
      michael_dawson authored 
      We were able to remove most of our changes needed to compile
on AIX with an earlier compiler level.  These changes are the
remaining ones.

The changes in heap/heap.cc are needed because otherwise the
compiler complains that result is potentially used before
it is initialized.

The changes in heap/mark-compact.cc are required because
AIX supports the full 64 bit address range so the check
being guarded is invalid.

The changes in build/toolchain.gypi and
test/cctest/cctest/gyp are aix only and are adjust the
compile/link options to allow the AIX build to succeed.

      Merge v8_optimized_debug 1 and 2 · aeb09e6d
      jochen authored 
      All builders that used level 1 should meanwhile define
v8_enable_slow_dchecks, and so they can use level 2 without losing
coverage. Level 2, however, is considerably faster, so we want to use it
on those builders as well. The make optdebug setting is not affected by
this change.
