2016-01-26Remove autoconf support for building runtime libraries.Chris Bieneman
Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I am the punishment of God... If [autoconf] had not committed great sins, God would not have sent a punishment like me upon [it]." -Genghis Khan Reviewers: chandlerc, grosbach, bob.wilson, zaks.anna, kubabrecka, samsonov, echristo Subscribers: iains, llvm-commits Differential Revision: http://reviews.llvm.org/D16473 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258863 91177308-0d34-0410-b5e6-96231b3b80d8

clang_darwin.mk Summary: This is the Makefile analog of r247833, except that the test also had to be changed such that clang actually attempts to link the program as opposed to just building it. Because of that change, I also switched the order to checking for ld/clang architecture support, because now lack of ld support would make the clang check fail. This fixes PR24776.

2015-04-01[UBSan] Embed UBSan into ASan runtime (compiler-rt part).Alexey Samsonov
Summary: Change the way we use ASan and UBSan together. Instead of keeping two separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on a platform, all UBSan sources are just compiled into dummy empty object files. UBSan initialization code (e.g. flag parsing) is directly called from ASan initialization, so we are able to enforce correct initialization order. This mirrors the approach we already use for ASan+LSan. This change doesn't modify the way we use standalone UBSan.

2015-01-23[compiler-rt] Ensure AsanInitFromRtl is called from a static initializer on ↵Kuba Brecka
OS X by using ASAN_DYNAMIC=1 The idea is to ensure that the ASan runtime gets initialized early (i.e. before other initializers/constructors) even when DYLD_INSERT_LIBRARIES is not used. In that case, the interceptors are not installed (on OS X, DYLD_INSERT_LIBRARIES is required for interceptors to work), and therefore ASan gets currently initialized quite late -- from the main executable's module initializer. The following issues are a consequence of this: https://code.google.com/p/address-sanitizer/issues/detail?id=363 https://code.google.com/p/address-sanitizer/issues/detail?id=357 Both of them are fixed with this patch.

2014-03-20PGO: Add explicit static initializationDuncan P. N. Exon Smith
Instead of relying on explicit static initialization from translation units, create a new file, InstrProfilingRuntime.cc, with an __llvm_pgo_runtime variable. After this commit (and its pair in clang), the driver will create a use of this variable. Unless the user defines their own version, the new object file will get pulled in, including that C++ static initialization that calls __llvm_pgo_register_write_atexit. The result is that, at least on Darwin, static initialization typically consists of a single function call, which registers a writeout functino atexit. Furthermore, users can skip even this behaviour by defining their own __llvm_pgo_runtime. <rdar://problem/15943240> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@204380 91177308-0d34-0410-b5e6-96231b3b80d8
