| | | | | | | | | | | to types which we can compute the size of. The comparison with zero isn't actually interesting here, it's mostly about putting sizeof into a sfinae context.

* [MC] Require an MCContext when constructing an MCDisassembler.Lang Hames2014-04-15
| | | | | | | | | | | | | | | | | | This patch re-introduces the MCContext member that was removed from MCDisassembler in r206063, and requires that an MCContext be passed in at MCDisassembler construction time. (Previously the MCContext member had been initialized in an ad-hoc fashion after construction). The MCCContext member can be used by MCDisassembler sub-classes to construct constant or target-specific MCExprs. This patch updates disassemblers for in-tree targets, and provides the MCRegisterInfo instance that some disassemblers were using through the MCContext (previously those backends were constructing their own MCRegisterInfo instances). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206241 91177308-0d34-0410-b5e6-96231b3b80d8

* [Allocator] Add Deallocate support to the AllocatorBase CRTP class,Chandler Carruth2014-04-15
| | | | | | | | | | | | along with templated overloads much like we have for Allocate. These will facilitate switching the Deallocate interface of all the Allocator classes to accept the size by pre-filling it from the type size where we can do so.

* [Allocator] Factor the Allocate template overloads into a base classChandler Carruth2014-04-15
| | | | | | | | | | | | | | | | | | | | rather than defining them (differently!) in both allocators. This also serves as a basis for documenting and even enforcing some of the LLVM-style "allocator" concept methods which must exist with various signatures. I plan on extending and changing the signatures of these to further simplify our allocator model in subsequent commits, so I wanted to factor things as best as I could first. Notably, I'm working to add the 'Size' to the deallocation method of all allocators. This has several implications not the least of which are faster deallocation times on certain allocation libraries (tcmalloc). It also will allow the JIT allocator to fully model the existing allocation interfaces and allow sanitizer poisoning of deallocated regions. The list of advantages goes on. =] But by factoring things first I'll be able to make this easier by first introducing template helpers for the deallocation path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206225 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | slabs rather than embedding a singly linked list in the slabs themselves. This has a few advantages: - Better utilization of the slab's memory by not wasting 16-bytes at the front. - Simpler allocation strategy by not having a struct packed at the front. - Avoids paging every allocated slab in just to traverse them for deallocating or dumping stats. The latter is the really nice part. Folks have complained from time to time bitterly that tearing down a BumpPtrAllocator, even if it doesn't run any destructors, pages in all of the memory allocated. Now it won't. =] Also resolves a FIXME with the scaling of the slab sizes. The scaling now disregards specially sized slabs for allocations larger than the threshold. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206147 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove redundant symbolization support from MCDisassembler interface.Lang Hames2014-04-11
| | | | | | | | | | | | | | | | | | | MCDisassembler has an MCSymbolizer member that is meant to take care of symbolizing during disassembly, but it also has several methods that enable the disassembler to do symbolization internally (i.e. without an attached symbolizer object). There is no need for this duplication, but ARM64 had been making use of it. This patch moves the ARM64 symbolization logic out of ARM64Disassembler and into an ARM64ExternalSymbolizer class, and removes the duplicated MCSymbolizer functionality from the MCDisassembler interface. Symbolization will now be done exclusively through MCSymbolizers. There should be no impact on disassembly for any platform, but this allows us to tidy up the MCDisassembler interface and simplify the process of (and invariants related to) disassembler setup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206063 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj][ELF] ELF Relocations Support.Simon Atanasyan2014-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch implements support for both relocation record formats: Elf_Rel and Elf_Rela. It is possible to define relocation against symbol only. Relocations against sections will be implemented later. Now yaml2obj recognizes X86_64, MIPS and Hexagon relocation types. Example of relocation section specification: Sections: - Name: .text Type: SHT_PROGBITS Content: "0000000000000000" AddressAlign: 16 Flags: [SHF_ALLOC] - Name: .rel.text Type: SHT_REL Info: .text AddressAlign: 4 Relocations: - Offset: 0x1 Symbol: glob1 Type: R_MIPS_32 - Offset: 0x2 Symbol: glob2 Type: R_MIPS_CALL16 The patch reviewed by Michael Spencer, Sean Silva, Shankar Easwaran. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206017 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement depth_first and inverse_depth_first range factory functions.David Blaikie2014-04-11
| | | | | | | | | | | | | | Also updated as many loops as I could find using df_begin/idf_begin - strangely I found no uses of idf_begin. Is that just used out of tree? Also a few places couldn't use df_begin because either they used the member functions of the depth first iterators or had specific ordering constraints (I added a comment in the latter case).

* Reimplement debug info compression by compressing the whole section, rather ↵David Blaikie2014-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | than a fragment. To support compressing the debug_line section that contains multiple fragments (due, I believe, to variation in choices of line table encoding depending on the size of instruction ranges in the actual program code) we needed to support compressing multiple MCFragments in a single pass. This patch implements that behavior by mutating the post-relaxed and relocated section to be the compressed form of its former self, including renaming the section. This is a more flexible (and less invasive, to a degree) implementation that will allow for other features such as "use compression only if it's smaller than the uncompressed data". Compressing debug_frame would be a possible further extension to this work, but I've left it for now. The hurdle there is alignment sections - which might require going as far as to refactor MCAssembler.cpp:writeFragment to handle writing to a byte buffer or an MCObjectWriter (there's already a virtual call there, so it shouldn't add substantial compile-time cost) which could in turn involve refactoring MCAsmBackend::writeNopData to use that same abstraction... which involves touching all the backends. This would remove the limited handling of fragment writing seen in ELFObjectWriter.cpp:getUncompressedData which would be nice - but it's more invasive. I did discover that I (perhaps obviously) don't need to handle relocations when I rewrite the fragments - since the relocations have already been applied and computed (and stored into ELFObjectWriter::Relocations) by this stage (necessarily, because we need to have written any immediate values or assembly-time relocations into the data already before we compress it, which we have). The test case doesn't necessarily cover that in detail - I can add more test coverage if that's preferred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205990 91177308-0d34-0410-b5e6-96231b3b80d8
