mt-sde: New file. 2007-08-17 Richard Sandiford <richard@codesourcery.com> Nigel Stephens <nigel@mips.com> * config/mt-sde: New file. * configure.ac (mips*-sde-elf*): New stanza. Use config/mt-sde as target_makefile_frag. * configure: Regenerate. gcc/ 2007-08-17 Richard Sandiford <richard@codesourcery.com> Nigel Stephens <nigel@mips.com> * config/mips/sde.h (DRIVER_SELF_SPECS): Add commas. Treat -mno-data-in-code and -mcode-xonly as aliases for -mcode-readable=no and -mcode-readable=pcrel respectively. * config/mips/t-sde (TARGET_LIBGCC2_CFLAGS): Add -mcode-xonly. (MULTILIB_OPTIONS): Add -mcode-readable=no multilibs. (MULTILIB_DIRNAMES): Update accordingly. Co-Authored-By: Nigel Stephens <nigel@mips.com> From-SVN: r127586

# We default to building libraries optimised for size. We switch off
# sibling-call optimization to permit interlinking of MIPS16 and
mt-sde (CFLAGS_FOR_TARGET): Add -mno-gpopt. config/ * mt-sde (CFLAGS_FOR_TARGET): Add -mno-gpopt. (CXXFLAGS_FOR_TARGET): Likewise. gcc/ * doc/invoke.texi: Document the MIPS -mlocal-sdata, -mextern-sdata and -mgpopt options. Adjust the -G documentation to match. * config/mips/mips.opt (mextern-data, mgpopt, mlocal-data): New. * config/mips/mips.c (mips_rtx_constant_in_small_data_p): New function, split out from mips_classify_symbol. Return false for !TARGET_LOCAL_SDATA. (mips_classify_symbol): Call mips_rtx_constant_in_small_data_p. Only use GP-relative accesses for non-pool symbols if TARGET_GPOPT. (override_options): Check whether the -mgpopt setting is consistent with the other flags. (symbolic_expression_p): Delete. (mips_select_rtx_section): Use mips_rtx_constant_in_small_data_p and default_elf_select_rtx_section. (mips_in_small_data_p): Honor section attributes for MIPS16 too. Return false for local data unless TARGET_LOCAL_SDATA. Likewise external data and TARGET_EXTERN_SDATA. gcc/testsuite/ * gcc.dg/attr-alias-3.c: Use real asm for MIPS. * gcc.target/mips/mips.exp (setup_mips_tests): Set mips_forced_gp and mips_forced_no_er. (dg-mips-options): Add -mno-abicalls when a small-data option is specified. Skip tests with small-data options if mips_forced_gp. Skip tests with -mexplicit-relocs if mips_forced_no_er. * gcc.target/mips/sdata-1.c: New test. * gcc.target/mips/sdata-2.c: Likewise. * gcc.target/mips/sdata-3.c: Likewise. * gcc.target/mips/sdata-4.c: Likewise.

# non-MIPS16 functions. The -mcode-xonly option allows MIPS16 libraries
# to run on Harvard-style split I/D memories, so long as they have the
# D-to-I redirect for PC-relative loads. -mno-gpopt has two purposes:
# it allows libraries to be used in situations where $gp != our _gp,
# and it allows them to be built with -G8 while retaining link compability
# with -G0 and -G4.
