Bill Budge 4899bcb66d Reland "[Memory] Use OS::Allocate for all OS memory allocations." ... This is a reland of 7e78506fc2 Original change's description: > [Memory] Use OS::Allocate for all OS memory allocations. > > - Eliminates OS::ReserveRegion and OS::ReserveAlignedRegion. > - Changes OS::Allocate to take alignment parameter, reorders parameters > to match page_allocator. > - Since the size of memory allocation can be deduced, don't return the > amount of memory allocated. > - Changes reservation of aligned address space. Before we would reserve > (size + alignment) rounded up to page size. This is too much, because > maximum misalignment is (alignment - page_size). > - On Windows and Cygwin, we release an oversize allocation and > immediately retry at the aligned address in the allocation. If we > lose the address due to a race, we just retry. > - Clean up all the calls to OS::Allocate in codegen and tests by adding > helper AllocateSystemPage function (allocation.h) and > AllocateAssemblerBuffer (cctest.h). > - Changes 'assm' to 'masm' in some targets for consistency when using > a macro-assembler. > > Bug: chromium:756050 > Cq-Include-Trybots: master.tryserver.chromium.linux:linux_chromium_rel_ng > Change-Id: I306dbe042cc867670fdc935abca29db074b0da71 > Reviewed-on: https://chromium-review.googlesource.com/749848 > Commit-Queue: Bill Budge <bbudge@chromium.org> > Reviewed-by: Michael Lippautz <mlippautz@chromium.org> > Reviewed-by: Hannes Payer <hpayer@chromium.org> > Cr-Commit-Position: refs/heads/master@{#49235} Bug: chromium:756050 Change-Id: I333f7a6aea0bcb608d01cafb43e94893a4625b15 Cq-Include-Trybots: master.tryserver.chromium.linux:linux_chromium_rel_ng Reviewed-on: https://chromium-review.googlesource.com/758509 Reviewed-by: Michael Lippautz <mlippautz@chromium.org> Commit-Queue: Bill Budge <bbudge@chromium.org> Cr-Commit-Position: refs/heads/master@{#49273}		2017-11-09 15:10:01 +00:00
