* Revert "Honor -fuse-init-array when os is not specified on x86"Mitch Phillips2019-12-171-0/+1
| | | | | | | This reverts commit aa5ee8f244441a8ea103a7e0ed8b6f3e74454516. This change broke the sanitizer buildbots. See comments at the patchset (https://reviews.llvm.org/D71360) for more information.
* Honor -fuse-init-array when os is not specified on x86Kamlesh Kumar2019-12-161-1/+0
| | | | | | | | | | | | | | | | | | | | | Currently -fuse-init-array option is not effective when target triple does not specify os, on x86,x86_64. i.e. // -fuse-init-array is not honored. $ clang -target i386 -fuse-init-array test.c -S // -fuse-init-array is honored. $ clang -target i386-linux -fuse-init-array test.c -S This patch fixes first case. And does cleanup. Reviewers: rnk, craig.topper, fhahn, echristo Reviewed By: rnk Differential Revision: https://reviews.llvm.org/D71360
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* Fix a bunch more layering of CodeGen headers that are in TargetDavid Blaikie2017-11-171-1/+1
| | | | | | | | All these headers already depend on CodeGen headers so moving them into CodeGen fixes the layering (since CodeGen depends on Target, not the other way around). llvm-svn: 318490

* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-1/+1
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic.

* CodeGen: simplify TargetMachine::getSymbol interface. NFC.Tim Northover2016-11-221-1/+1
| | | | | | | | | No-one actually had a mangler handy when calling this function, and getSymbol itself went most of the way towards getting its own mangler (with a local TLOF variable) so forcing all callers to supply one was just extra complication. llvm-svn: 287645

* move getNameWithPrefix and getSymbol to TargetMachine.Rafael Espindola2014-02-191-1/+1
| | | | | | | | | | TargetLoweringBase is implemented in CodeGen, so before this patch we had a dependency fom Target to CodeGen. This would show up as a link failure of llvm-stress when building with -DBUILD_SHARED_LIBS=ON. This fixes pr18900. llvm-svn: 201711
* Add back r201608, r201622, r201624 and r201625Rafael Espindola2014-02-191-4/+6
| | | | | | | | | | | | | | r201608 made llvm corretly handle private globals with MachO. r201622 fixed a bug in it and r201624 and r201625 were changes for using private linkage, assuming that llvm would do the right thing. They all got reverted because r201608 introduced a crash in LTO. This patch includes a fix for that. The issue was that TargetLoweringObjectFile now has to be initialized before we can mangle names of private globals. This is trivially true during the normal codegen pipeline (the asm printer does it), but LTO has to do it manually. llvm-svn: 201700
* Revert r201622 and r201608.Daniel Jasper2014-02-191-6/+4
| | | | | | | This causes the LLVMgold plugin to segfault. More information on the replies to r201608. llvm-svn: 201669
* Fix PR18743.Rafael Espindola2014-02-181-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | The IR @foo = private constant i32 42 is valid, but before this patch we would produce an invalid MachO from it. It was invalid because it would use an L label in a section where the liker needs the labels in order to atomize it. One way of fixing it would be to just reject this IR in the backend, but that would not be very front end friendly. What this patch does is use an 'l' prefix in sections that we know the linker requires symbols for atomizing them. This allows frontends to just use private and not worry about which sections they go to or how the linker handles them. One small issue with this strategy is that now a symbol name depends on the section, which is not available before codegen. This is not a problem in practice. The reason is that it only happens with private linkage, which will be ignored by the non codegen users (llvm-nm and llvm-ar). llvm-svn: 201608
* Use a consistent argument order in TargetLoweringObjectFile.Rafael Espindola2014-02-091-9/+7
| | | | | | | | | These methods normally call each other and it is really annoying if the arguments are in different order. The more common rule was that the arguments specific to call are first (GV, Encoding, Suffix) and the auxiliary objects (Mang, TM) come after. This patch changes the exceptions. llvm-svn: 201044
* Pass the Mangler by reference.Rafael Espindola2014-02-081-3/+3
| | | | | | | It is never null and it is not used in casts, so there is no reason to use a pointer. This matches how we pass TM. llvm-svn: 201025
* [Sparc] Use %r_disp32 for pc_rel entries in gcc_except_table and eh_frame.Venkatraman Govindaraju2014-01-291-0/+43
Otherwise, assembler (gas) fails to assemble them with error message "operation combines symbols in different segments". This is because MC computes pc_rel entries with subtract expression between labels from different sections. llvm-svn: 200373
