Musl and lld don't support TLS copy relocs, and don't want to add support for this feature which is unique to RISC-V. Only GNU ld and glibc support them. In the pasbi discussion, people have pointed out various problems with using them, so we are deprecating them. There doesn't seem to be an ABI break from dropping them so this patch modifies gcc to stop creating them. I'm using an ifdef for now in case a problem turns up and the code has to be re-enabled. The plan is to add an initial to local exec relaxation as a replacement, though this has not been defined or implemented yet. gcc/ * config/riscv/riscv.c (riscv_legitimize_tls_address): Ifdef out use of TLS_MODEL_LOCAL_EXEC when not pic.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
