Thomas Petazzoni 543bc7c921 gcc/4.8: fix C++ exceptions and pthread_exit() ... Following the introduction of the support for the musl C library, the support of C++ exceptions or features like pthread_exit() got broken even with other libraries such as glibc. This was reported as bug #7028. The problem was caused by the gcc patch needed to add support for musl, which modified the libgcc/unwind-dw2-fde-dip.c logic to decide whether USE_PT_GNU_EH_FRAME should be enabled or not. It completely removed the existing logic, replacing it by a single logic based on the definition of TARGET_DL_ITERATE_PHDR. However, this constant gets defined by the configure script only for Solaris, or Linux Musl platforms. For glibc/uClibc, the configure script does not define it, and therefore USE_PT_GNU_EH_FRAME is not defined, causing issues with exception handling. This patch fixes that by restoring all the logic of libgcc/unwind-dw2-fde-dip.c, and just adding the musl logic as one more case. It has been successfully runtime tested using the two code examples provided in bug #7208, with uClibc, musl and glibc.
