* Install new LLVM license structure and new developer policy.Chandler Carruth2019-01-191-16/+236
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This installs the new developer policy and moves all of the license files across all LLVM projects in the monorepo to the new license structure. The remaining projects will be moved independently. Note that I've left odd formatting and other idiosyncracies of the legacy license structure text alone to make the diff easier to read. Critically, note that we do not in any case *remove* the old license notice or terms, as that remains necessary until we finish the relicensing process. I've updated a few license files that refer to the LLVM license to instead simply refer generically to whatever license the LLVM project is under, basically trying to minimize confusion. This is really the culmination of so many people. Chris led the community discussions, drafted the policy update and organized the multi-year string of meeting between lawyers across the community to figure out the strategy. Numerous lawyers at companies in the community spent their time figuring out initial answers, and then the Foundation's lawyer Heather Meeker has done *so* much to help refine and get us ready here. I could keep going on, but I just want to make sure everyone realizes what a huge community effort this has been from the begining.

* [hwasan] Madvise away unused shadow.Evgeniy Stepanov2019-01-194-1/+100
| | | | | | | | | | | | | | | | | | Summary: Whenever a large shadow region is tagged to zero, madvise(DONT_NEED) as much of it as possible. This reduces shadow RSS on Android by 45% or so, and total memory use by 2-4%, probably even more on long running multithreaded programs. CPU time seems to be in the noise.

* Fix sanitizer tool list used to generate sanitizer_common tests to be ↵Dan Liew2019-01-166-14/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | up-to-date. Summary: This replaces the sanitizer tool list (used for generating sanitizer_common configurations) with a tool list derived from existing build system information. Previously sanitizer_common had its own list of supported sanitizer tools. This was bad because it was out of sync with the rest of the build system. Notably it meant that the sanitizer_common runtime was only being tested on Darwin the ASan dylib and not the other sanitizer dylibs that are built for Darwin (LSan, TSan, and UBSan). Unfortunately enabling the tests against other sanitizer dylibs has lead to some test failures on Darwin. For now they've been marked as XFAIL until the failures can investigated properly. For Windows and Android we use the old sanitizer tool list to try avoid bot breakages. rdar://problem/47143078 Reviewers: kubamracek, george.karpenkov, yln, samsonov, vitalybuka, krytarowski Subscribers: srhines, mgorny, fedor.sergeev, #sanitizers, llvm-commits Differential Revision: https://reviews.llvm.org/D55740 llvm-svn: 351398

| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the compiler-rt part. The clang part is D54589. This is a second commit, the original one was r351106, which was mass-reverted in r351159 because 2 compiler-rt tests were failing. Now, i have fundamentally changed the testing approach: i malloc a few bytes, intentionally mis-align the pointer (increment it by one), and check that. Also, i have decreased the expected alignment. This hopefully should be enough to pacify all the bots. If not, i guess i might just drop the two 'bad' tests.

| | | | | | | | | | | | | | | | | Disable tests requiring sunrpc when the relevant headers are missing. In order to accommodate that, move the header check from sanitizer_common to base-config-ix, and define the check result as a global variable there. Use it afterwards both for definition needed by sanitizer_common, and to control 'sunrpc' test feature. While at it, remove the append_have_file_definition macro that was used only once, and no longer fits the split check-definition.

| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This fixes linker errors that occurs when the `sanitizer_type_traits_test.cc` is built without optimizations. The error occurs because the test tries to take a reference. A possible workaround is to give the GTest macros take boolean rvalues by doing something like: ``` ASSERT_TRUE(bool(is_same<uptr, uptr>::value)); ``` However this only hides the problem. Unfortunately Using `constexpr` won't fix the problem unless we are using C++17.

| | | | | | | | | | | | | | | | | | This patch implements the __uint128_t __fixunstfti (long double) method for PowerPC -- specifically to convert a long double (IBM double-double) to an unsigned 128 bit integer. The general approach of this algorithm is to convert the high and low doubles of the long double and add them together if the doubles fit within 64 bits. However, additional adjustments and scaling is performed when the high or low double does not fit within a 64 bit integer.
