There seems no real reason to require -mexplicit-relocs=always for -mcmodel=extreme or model attribute. As the linker does not know how to relax a 3-operand la.local or la.global pseudo instruction, just emit explicit relocs for SYMBOL_PCREL64, and under TARGET_CMODEL_EXTREME also SYMBOL_GOT_DISP. gcc/ChangeLog: * config/loongarch/loongarch.cc (loongarch_explicit_relocs_p): Return true for SYMBOL_PCREL64. Return true for SYMBOL_GOT_DISP if TARGET_CMODEL_EXTREME. (loongarch_split_symbol): Check for la_opt_explicit_relocs != EXPLICIT_RELOCS_NONE instead of TARGET_EXPLICIT_RELOCS. (loongarch_print_operand_reloc): Likewise. (loongarch_option_override_internal): Likewise. (loongarch_handle_model_attribute): Likewise. * doc/invoke.texi (-mcmodel=extreme): Update the compatibility between it and -mexplicit-relocs=. gcc/testsuite/ChangeLog: * gcc.target/loongarch/attr-model-3.c: New test. * gcc.target/loongarch/attr-model-4.c: New test. * gcc.target/loongarch/func-call-extreme-3.c: New test. * gcc.target/loongarch/func-call-extreme-4.c: New test.
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.
