2019-11-12 Corentin Gay <gay@adacore.com> Jerome Lambourg <lambourg@adacore.com> Olivier Hainque <hainque@adacore.com> libgcc/ * config/t-gthr-vxworks: New file, add all the gthr-vxworks sources to LIB2ADDEH. * config/t-vxworks: Remove adjustments to LIB2ADDEH. * config/t-vxworks7: Likewise. * config.host: Append a block at the end of the file to add the t-gthr files to the tmake_file list for VxWorks after everything else. * config/vxlib.c: Rename as gthr-vxworks.c. * config/vxlib-tls.c: Rename as gthr-vxworks-tls.c. * config/gthr-vxworks.h: Simplify a few comments. Expose a TAS API and a basic error checking API, both internal. Simplify the __gthread_once_t type definition and initializers. Add sections for condition variables support and for the C++0x thread support, conditioned against Vx653 for the latter. * config/gthr-vxworks.c (__gthread_once): Simplify comments and implementation, leveraging the TAS internal API. * config/gthr-vxworks-tls.c: Introduce an internal TLS data access API, leveraging the general availability of TLS services in VxWorks7 post SR6xxx. (__gthread_setspecific, __gthread_setspecific): Use it. (tls_delete_hook): Likewise, and simplify the enter/leave dtor logic. * config/gthr-vxworks-cond.c: New file. GTHREAD_COND variable support based on VxWorks primitives. * config/gthr-vxworks-thread.c: New file. GTHREAD_CXX0X support based on VxWorks primitives.
