Bug ID: 22009
Summary: Migrate the rest of tsan tests to cmake/lit
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Part of tsan tests were migrated to cmake/lit (output tests), but the rest is
left in 'make presubmit'. This is effectively equivalent to removal of part of
useful tests as people started to ignore 'make presubmit'.
First, Go runtime become broken:
(cd go && ./buildgo.sh)
gcc gotsan.cc -c -o race_linux_amd64.syso -I../rtl -I../..
-I../../sanitizer_common -I../../../include -std=c++11 -m64 -Wall
-fno-exceptions -fno-rtti -DSANITIZER_GO -DTSAN_SHADOW_COUNT=4
-DSANITIZER_DEADLOCK_DETECTOR_VERSION=2 -fPIC -ffreestanding
-Wno-maybe-uninitialized -Wno-unused-const-variable -Werror
-Wno-unknown-warning-option -DTSAN_DEBUG=0 -O3 -msse3 -fomit-frame-pointer
race_linux_amd64.syso: In function `__sanitizer::internal_start_thread(void
(*)(void*), void*)':
gotsan.cc:(.text+0x104d6): undefined reference to
`__sanitizer::real_pthread_create(void*, void*, void* (*)(void*), void*)'
race_linux_amd64.syso: In function `__sanitizer::internal_join_thread(void*)':
gotsan.cc:(.text+0x10503): undefined reference to
`__sanitizer::real_pthread_join(void*, void**)'
collect2: error: ld returned 1 exit status
Now the rest become broken:
(ulimit -s 8192; ./tsan_test)
==18778==FATAL: ThreadSanitizer: failed to intercept memcpy
make[1]: *** [run] Error 1
Please finish the migration to cmake/lit: restore what 'make presubmit' does:
presubmit:
../sanitizer_common/scripts/check_lint.sh
# Debug build with clang.
$(MAKE) -f Makefile.old clean
$(MAKE) -f Makefile.old run DEBUG=1 -j 16 CC=$(CLANG) CXX=$(CLANG)++
# Release build with clang.
$(MAKE) -f Makefile.old clean
$(MAKE) -f Makefile.old run DEBUG=0 -j 16 CC=$(CLANG) CXX=$(CLANG)++
./check_memcpy.sh
# Debug build with gcc
$(MAKE) -f Makefile.old clean
$(MAKE) -f Makefile.old run DEBUG=1 -j 16 CC=gcc CXX=g++
# Release build with gcc
$(MAKE) -f Makefile.old clean
$(MAKE) -f Makefile.old run DEBUG=0 -j 16 CC=gcc CXX=g++
./check_memcpy.sh
./check_analyze.sh
# Sanity check for Go runtime
(cd go && ./buildgo.sh)
and run tests with -O0/-O2 as asan does.
