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.
