<p class="MsoNormal"><span style="font-size:11.0pt">I have a problem with tsan library contains .preinit_array section even with PIC build, and found that SANITIZER_CAN_USE_PREINIT_ARRAY macro is guarded by PIC macro (<a href="https://github.com/llvm-mirror/compiler-rt/blob/master/lib/sanitizer_common/sanitizer_internal_defs.h#L100">https://github.com/llvm-mirror/compiler-rt/blob/master/lib/sanitizer_common/sanitizer_internal_defs.h#L100</a>).
I assumed that PIC macro to be defined if COMPILER_RT_HAS_FPIC_FLAG is set, but it seems that PIC macro is never defined unless it is explicitly given by the build command line – I couldn’t find any place that defines the macro from cmake files. Is that expected,
or something is missed here? Thanks!<o:p></o:p></span></p>
