The BFD fix eliminates the link failure and working code is generated at -O0, but _not_ when optimization is enabled because the optimizer changes: movq .refptr._ZTH1s(%rip), %rax testq %rax, %rax je .L2 call _ZTH1s into: leaq _ZTH1s(%rip), %rax testq %rax, %rax je .L2 call _ZTH1s and the leaq now also gets the relocation overflow. So the fix is to teach legitimate_pic_address_disp_p to reject the transformation when the symbol is an external weak function, which yields: cmpq $0, .refptr._ZTH1s(%rip) je .L2 call _ZTH1s and the cmpq keeps a relocation that does not overflow. gcc/ PR c++/64697 * config/i386/i386.c (legitimate_pic_address_disp_p): For PE-COFF do not return true for external weak function symbols in medium model. |

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.
