[sanitizers] Make it possible to XFAIL on the effective target, not just the default.
...
Summary:
The triple is not the right thing to XFAIL on since LIT only sees the default
triple and not the effective triple chosen by any -target option in the RUN
directives. This discrepancy is shown in the table below:
Default Triple | Options | XFAIL | LIT's expected result | Desired expectation
=================+===================================+========+=======================+====================
mips-linux-gnu | -target mips-linux-gnu | | Pass | Pass
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | | Pass | Pass
mips-linux-gnu | -target mips-linux-gnu | mips | Fail | Fail
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips | Fail | Fail/Pass* (debatable**)
mips-linux-gnu | -target mips-linux-gnu | mips- | Fail | Fail
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips- | Fail | Pass*
mips-linux-gnu | -target mips-linux-gnu | mips64 | Pass | Pass
mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips64 | Pass | Fail*
mips64-linux-gnu | -target mips-linux-gnu | | Pass | Pass
mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | | Pass | Pass
mips64-linux-gnu | -target mips-linux-gnu | mips | Fail | Fail*
mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips | Fail | Fail/Pass (debatable**)
mips64-linux-gnu | -target mips-linux-gnu | mips- | Pass | Fail*
mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips- | Pass | Pass
mips64-linux-gnu | -target mips-linux-gnu | mips64 | Fail | Pass*
mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips64 | Fail | Fail
x64_64-linux-gnu | -target i386-linux-gnu | | Pass | Pass
x64_64-linux-gnu | -target x86_64-linux-gnu | | Pass | Pass
x64_64-linux-gnu | -target i386-linux-gnu | i386 | Pass | Fail*
x64_64-linux-gnu | -target x86_64-linux-gnu | i386 | Pass | Pass
x64_64-linux-gnu | -target i386-linux-gnu | x86_64 | Fail | Pass
x64_64-linux-gnu | -target x86_64-linux-gnu | x86_64 | Fail | Fail*
* These all differ from LIT's current behaviour.
** People's expectations vary depending on whether they know that LIT does a
substring match on the default triple or think it's an exact match on an
architecture.
This patch adds "target-is-${target_arch}" to the available features list and
updates the mips XFAIL's to use them. XFAIL'ing on these features will
correctly account for the target being tested. Making the table:
Options | XFAIL | LIT's expected result
==================================+==================+======================
-target mips-linux-gnu | | Pass
-target mips64-linux-gnu -mabi=64 | | Pass
-target mips-linux-gnu | target-is-mips | Fail
-target mips64-linux-gnu -mabi=64 | target-is-mips | Pass
-target mips-linux-gnu | target-is-mips64 | Pass
-target mips64-linux-gnu -mabi=64 | target-is-mips64 | Fail
-target i386-linux-gnu | | Pass
-target x86_64-linux-gnu | | Pass
-target i386-linux-gnu | target-is-i386 | Fail
-target x86_64-linux-gnu | target-is-i386 | Pass
-target i386-linux-gnu | target-is-x86_64 | Pass
-target x86_64-linux-gnu | target-is-x86_64 | Fail

[compiler-rt] [tsan] Enable intercept setjmp/longjmp for AArch64
...
This patch adds assembly routines to enable setjmp/longjmp for aarch64
on linux. It fixes:
* test/tsan/longjmp2.cc
* test/tsan/longjmp3.cc
* test/tsan/longjmp4.cc
* test/tsan/signal_longjmp.cc
I also checked with perlbench from specpu2006 (it fails to run
with missing setjmp/longjmp intrumentation).

[tsan] Enable tsan for aarch64
...
This patch enabled TSAN for aarch64 with 39-bit VMA layout. As defined by
tsan_platform.h the layout used is:
0000 4000 00 - 0200 0000 00: main binary
2000 0000 00 - 4000 0000 00: shadow memory
4000 0000 00 - 5000 0000 00: metainfo
5000 0000 00 - 6000 0000 00: -
6000 0000 00 - 6200 0000 00: traces
6200 0000 00 - 7d00 0000 00: -
7d00 0000 00 - 7e00 0000 00: heap
7e00 0000 00 - 7fff ffff ff: modules and main thread stack
Which gives it about 8GB for main binary, 4GB for heap and 8GB for
modules and main thread stack.
Most of tests are passing, with the exception of:
* ignore_lib0, ignore_lib1, ignore_lib3 due a kernel limitation for
no support to make mmap page non-executable.
* longjmp tests due missing specialized assembly routines.
These tests are xfail for now.
The only tsan issue still showing is:
rtl/TsanRtlTest/Posix.ThreadLocalAccesses
Which still required further investigation. The test is disable for
aarch64 for now.
