7314	[compiler-rt] Fix 64-bits exception handlers in ASAN 64-bits... [compiler-rt] Fix 64-bits exception handlers in ASAN 64-bits runtime Summary: This is adding the appropriate suport for exception handling for 64-bits ASAN on windows.

7313	[compiler-rt] Fix incorrect handling of indirect load. [compiler-rt] Fix incorrect handling of indirect load. Summary: Indirect load are relative offset from RIP. The current trampoline implementation is incorrectly copying these instructions which make some unittests crashing. This patch is not fixing the unittests but it's fixing the crashes. The functions are no longer hooked. Patches will come soon to fix these unittests.

7312	TestCase null_deref was failing in Win64: TestCase null_deref was failing in Win64: c:\lipo\work\asan\b_llvm>c:\lipo\work\asan\b_llvm\projects\compiler-rt\test\asan\X86_64WindowsConfig\TestCases\Output\null_deref.cc.tmp ================================================================= ==5488==ERROR: AddressSanitizer: access-violation on unknown address 0x000000000028 (pc 0x7ff701f91067 bp 0x000c8cf8fbf0 sp 0x000c8cf8fbb0 T0) ==5488==The signal is caused by a READ memory access. ==5488==Hint: address points to the zero page. #0 0x7ff701f91066 in NullDeref(int *) C:\lipo\work\asan\llvm\projects\compiler-rt\test\asan\TestCases\null_deref.cc:15:10 #1 0x8a0388830a67 (<unknown module>) The reason was symbols was not initilized. In fact, it was first inited with a call to stack.Print(), which calls WinSymbolizerTool::SymbolizePC, then InitializeDbgHelpIfNeeded(). Since the StackWalk was performed before the stack.Print(), stack frames where not gathered correctly. There should be a better place to initialize symbols. For now, this patch makes the test happy.

7311	[asan] Reduce flakiness of halt_on_error-torture.cc testcase... [asan] Reduce flakiness of halt_on_error-torture.cc testcase. It seems in some situations we have clashes on very first error so test only prints "nested bug in the same thread, aborting" rather than "use-after-poison", so remove corresponding " RUN: FileCheck %s < 10.txt" line. Also, the two last " RUN: FileCheck --check-prefix=CHECK-COLLISION %s < 1.txt \|\| FileCheck --check-prefix=CHECK-NO-COLLISION %s < 1.txt" look wrong, they should check 10.txt. Fix these lines too.

7310	[asan] Avoid hooking memchr() on Windows64 [asan] Avoid hooking memchr() on Windows64 There is not enough padding in front of memchr(), and, the first 6 bytes contains a branch instruction. Basically the current interception will not work on memchr(). It was disabled before, but was missing the part to disable it for INTERCEPT_LIBRARY_FUNCTION.

7308	[compiler-rt] Fix missing argument in asan unittest [compiler-rt] Fix missing argument in asan unittest Summary: Both test have the same command-line. The second test is missing the /GS-. Keep in mind that /GS is on by default. Reviewers: rnk Subscribers: llvm-commits, wang0109, kubabrecka, chrisha Differential Revision: https://reviews.llvm.org/D22339	etienneb	7 years ago
7307	[compiler-rt] Add more assembly patterns for interception [compiler-rt] Add more assembly patterns for interception Summary: These patterns are encounter when using instrumented DLL. Without this patch, asan lit test are crashing when trying to hook on RaiseException function.

7306	[compiler-rt] Add internal wcslen to avoid crashing on windo... [compiler-rt] Add internal wcslen to avoid crashing on windows 64-bits Summary: The function wcslen is incorrectly hooked on windows 64-bits. The interception library is not able to hook without breaking the code. The function is too small and the interception must be done with trampoline-hooking which turned out to be incorrect on a small loop (first few instructions have a backedge).

[compiler-rt] Fix missing frame with stackwalking on windows 64-bits Summary: Fix missing frame with stackwalking on windows 64-bits Reviewers: rnk Subscribers: llvm-commits, wang0109, kubabrecka, chrisha Differential Revision: https://reviews.llvm.org/D22358	etienneb	7 years ago
7304	Add runtime support for __cpu_model (__builtin_cpu_supports) Add runtime support for __cpu_model (__builtin_cpu_supports) Summary: This aims to add support for __cpu_model and address Bug 25510. It uses the code from lib/Support/Host.cpp for cpu detection, and creates __cpu_model with that info. Tested on OSX and built on Linux as well (though libgcc is the default). The use of "asm" required -std=gnu99, hence the cmake change. Corrections on better addressing this are welcome. Previously reverted, up for review again to iron out outstanding issues.

7303	Replace -mllvm -asan-use-after-scope=1 with -fsanitize-addre... Replace -mllvm -asan-use-after-scope=1 with -fsanitize-address-use-after-scope Summary: When test was added we had no -fsanitize-address-use-after-scope in clang so we had to use -mllvm -asan-use-after-scope=1.

7301	[RT-ARM] Syntax unified for aeabi_mem* functions [RT-ARM] Syntax unified for aeabi_mem* functions Use unified syntax for builtins/arm/aeabi_mem*.S. This makes these files consistent with the others. This fixes a problem on the linker, which can fail with the message "relocation truncated to fit: R_ARM_THM_JUMP11 against symbol" Patch by Kor Nielsen.	rengolin	7 years ago
7300	[sanitizers] Allocate 12MB for stack instead of 134MB [sanitizers] Allocate 12MB for stack instead of 134MB The thread registry test was failing to allocate 25 threads with stack size 134MB, which is pretty reasonable. Also print the error code in our pthread wrappers in case this happens again.	rnk	7 years ago
7299	[asan] Fix interception unittest on Windows64. [asan] Fix interception unittest on Windows64. mov edi,edi is _not_ NOP in 64-bit, use 66,90h instead. This bug was causing interception unittest to crash on Windows64 (windows 8 and windows 10). Credits to etienneb for finding the root cause.

7297	[compiler-rt] Disable a test failing on windows. [compiler-rt] Disable a test failing on windows. Summary: The unittest is not working on windows. The "regexp.h" is not available and gtest-port won't support regexp with operator '\|'. The test wasn't failing on 32-bits because of this check: ``` if (SANITIZER_WORDSIZE != 64 \|\| ASAN_AVOID_EXPENSIVE_TESTS) return; ``` ``` [ RUN ] AddressSanitizer.HugeMallocTest C:/src/llvm/llvm/utils/unittest/googletest\src/gtest-port.cc(272): error: Failed Syntax error at index 30 in simple regular expression "is located 1 bytes to the left\|AddressSanitizer failed to allocate": '\|' is unsupported. C:/src/llvm/llvm/projects/compiler-rt/lib/asan/tests/asan_test.cc(308): error: Death test: Ident((char*)malloc(n_megs << 20))[-1] = 0 Result: died but not with expected error. Expected: is located 1 bytes to the left\|AddressSanitizer failed to allocate ``` See gtest-port.h: ``` #elif GTEST_OS_WINDOWS // <regex.h> is not available on Windows. Use our own simple regex // implementation instead. # define GTEST_USES_SIMPLE_RE 1 ``` Reviewers: rnk Subscribers: llvm-commits, wang0109, kubabrecka, chrisha Differential Revision: http://reviews.llvm.org/D22257	etienneb	7 years ago
7296	[compiler-rt] Enhance function padding detection for functio... [compiler-rt] Enhance function padding detection for function interception Summary: Many CRT (64-bits) functions contains a "hint-nop". The current padding detection is not able to recognize the 10-bytes padding and the HotPatch hooking technique cannot be used. Other patterns may be discover and may be added later.
