See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done
and manually updated (many) references to renamed files found by that.

I noticed that the instance of OpenFile in sanitizer_solaris.cc is no
longer needed.
Removed as follows, tested on x86_64-pc-solaris2.11.

Both LLVM 8.0.0 and current trunk fail to link libclang_rt.ubsan.standalone-*.so
on Solaris 11/x86 with GCC 8.1.0:
Undefined first referenced
symbol in file
Scanning dependencies of target clang_rt.asan_cxx-x86_64
__sanitizer::internal_dup(int) ../sanitizer_common/CMakeFiles/RTSanitizerCommon.i386.dir/sanitizer_posix.cc.o
ld: fatal: symbol referencing errors
collect2: error: ld returned 1 exit status
make[2]: *** [projects/compiler-rt/lib/ubsan/CMakeFiles/clang_rt.ubsan_standalone-dynamic-i386.dir/build.make:233: lib/clang/9.0.0/lib/sunos/libclang_rt.ubsan_standalone-i386.so] Error 1
Fixed by providing an implementation, which allowed the i386-pc-solaris2.11 build
to finish.

to reflect the new license.
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.

Summary:
Support running with no open file descriptors (as may happen to
"init" process on linux).
* Remove a check that writing to stderr succeeds.
* When opening a file (ex. for log_path option), dup the new fd out of
[0, 2] range to avoid confusing the program.
(2nd attempt, this time without the sanitizer_rtems change)

This reverts commit r349699.
Reason: the commit breaks compilation of sanitizer_rtems.cc when
building for RTEMS.

While testing the Solaris libsanitizer port on GCC mainline, I found that
I'd messed up
the largefile checks in various ways, some of which showed as compile failures
(wrong structure sizes and member offsets), others at runtime, some of those only
on sparc as a big-endian target.
This patch fixes all of them:
- OFF_T is now correctly defined for 32-bit largefile and traditional
environments, and 64-bit.
- The definition of __sanitizer_dirent now checks the correct conditionals.
- sanitizer_procmaps_solaris.cc undefines _FILE_OFFSET_BITS: before
Solaris 11.4 <procfs.h> doesn't even compile with largefile support
enabled, but the use at hand doesn't need it anyway while g++ 9 will
define _FILE_OFFSET_BITS=64 out of the box.
- With full largefile support enabled, one needs to use e.g. mmap64
instead of mmap; this is hidden behind macros.
With this patch I could bootstrap gcc mainline on both sparc-sun-solaris2.11 and
i386-pc-solaris2.11. In addition, I've successfully built llvm on
i386-pc-solaris2.11.

Summary:
This is the first mostly working version of the Sanitizer port to 32-bit Solaris/x86.
It is currently based on Solaris 11.4 Beta.
This part was initially developed inside libsanitizer in the GCC tree and should apply to
both. Subsequent parts will address changes to clang, the compiler-rt build system
and testsuite.
I'm not yet sure what the right patch granularity is: if it's profitable to split the patch
up, I'd like to get guidance on how to do so.
Most of the changes are probably straightforward with a few exceptions:
* The Solaris syscall interface isn't stable, undocumented and can change within an
OS release. The stable interface is the libc interface, which I'm using here, if possible
using the internal _-prefixed names.
* While the patch primarily target 32-bit x86, I've left a few sparc changes in. They
cannot currently be used with clang due to a backend limitation, but have worked
fine inside the gcc tree.
* Some functions (e.g. largefile versions of functions like open64) only exist in 32-bit
Solaris, so I've introduced a separate SANITIZER_SOLARIS32 to check for that.
The patch (with the subsequent ones to be submitted shortly) was tested
on i386-pc-solaris2.11. Only a few failures remain, some of them analyzed, some
still TBD:
AddressSanitizer-i386-sunos :: TestCases/Posix/concurrent_overflow.cc
AddressSanitizer-i386-sunos :: TestCases/init-order-atexit.cc
AddressSanitizer-i386-sunos :: TestCases/log-path_test.cc
AddressSanitizer-i386-sunos :: TestCases/malloc-no-intercept.c
AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/concurrent_overflow.cc

AddressSanitizer-i386-sunos-dynamic :: TestCases/log-path_test.cc
AddressSanitizer-i386-sunos-dynamic :: TestCases/malloc-no-intercept.c
SanitizerCommon-Unit :: ./Sanitizer-i386-Test/MemoryMappingLayout.DumpListOfModules
SanitizerCommon-Unit :: ./Sanitizer-i386-Test/SanitizerCommon.PthreadDestructorIterations
Maybe this is good enough the get the ball rolling.
