* [compiler-rt][builtins] Provide __clear_cache for SPARCRainer Orth2019-07-231-0/+10
| | | | | | | | | | | | | | | | While working on https://reviews.llvm.org/D40900, two tests were failing since __clear_cache aborted. While libgcc's __clear_cache is just empty, this only happens because gcc (in gcc/config/sparc/sparc.c (sparc32_initialize_trampoline, sparc64_initialize_trampoline)) emits flush insns directly. The following patch mimics that. Tested on sparcv9-sun-solaris2.11.

* Update more file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | | to reflect the new license. These used slightly different spellings that defeated my regular expressions. 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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@351648 91177308-0d34-0410-b5e6-96231b3b80d8

This matches the example code at http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.den0024a/BABJDBHI.html, and also matches what libgcc does.

* Fix checks for Android.Dan Albert2014-10-201-4/+4
| | | | | | | | | | | | | __ANDROID__ is a define that comes from the toolchain when building for Android targets. ANDROID has a different meaning. ANDROID is defined for _every_ Android build, including those done for host modules. For host modules, we want to build the regular Linux sanitizers and builtins, not the one for Android devices. This hasn't been a problem until now because we only just started building the sanitizers for the host. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@220203 91177308-0d34-0410-b5e6-96231b3b80d8
