* mips.h (M_ACLR_OB, M_ASET_OB, M_CACHE_OB, M_CACHEE_OB, M_L_DOB) (M_LB_A, M_LBE_OB, M_LBU_A, M_LBUE_OB, M_LD_A, M_LD_OB, M_LDC2_OB) (M_LDL_OB, M_LDM_OB, M_LDP_OB, M_LDR_OB, M_LH_A, M_LHE_OB, M_LHU_A) (M_LHUE_OB, M_LL_OB, M_LLD_OB, M_LLE_OB, M_LS_A, M_LW_A, M_LWE_OB) (M_LWC0_A, M_LWC1_A, M_LWC2_A, M_LWC2_OB, M_LWC3_A, M_LWL_A, M_LWL_OB) (M_LWLE_OB, M_LWM_OB, M_LWP_OB, M_LWR_A, M_LWR_OB, M_LWRE_OB, M_LWU_OB) (M_PREF_OB, M_PREFE_OB, M_S_DOB, M_SAA_OB, M_SAAD_OB, M_SC_OB) (M_SCD_OB, M_SCE_OB, M_SD_A, M_SD_OB, M_SDC2_OB, M_SDL_OB, M_SDM_OB) (M_SDP_OB, M_SDR_OB, M_SB_A, M_SBE_OB, M_SH_A, M_SHE_OB, M_SW_A) (M_SWE_OB, M_SWC0_A, M_SWC1_A, M_SWC2_A, M_SWC2_OB, M_SWC3_A, M_SWL_A) (M_SWL_OB, M_SWLE_OB, M_SWM_OB, M_SWP_OB, M_SWR_A, M_SWR_OB, M_SWRE_OB) (M_ULD, M_ULH, M_ULHU, M_ULW, M_USH, M_USW, M_USD): Delete. (M_ULD_A, M_ULH_A, M_ULHU_A, M_ULW_A, M_USH_A, M_USW_A, M_USD_A): Rename to... (M_ULD_AB, M_ULH_AB, M_ULHU_AB, M_ULW_AB, M_USH_AB, M_USW_AB) (M_USD_AB): ...these. opcodes/ * mips-opc.c (mips_builtin_opcodes): Remove o(b) macros. Move LD and SD A(B) macros up. * micromips-opc.c (micromips_opcodes): Likewise. gas/ * config/tc-mips.c (gprel16_reloc_p): New function. (macro_read_relocs): Assume BFD_RELOC_LO16 if all relocs are BFD_RELOC_UNUSED. (offset_high_part, small_offset_p): New functions. (nacro): Use them. Remove *_OB and *_DOB cases. For single- register load and store macros, handle the 16-bit offset case first. If a 16-bit offset is not suitable for the instruction we're generating, load it into the temporary register using ADDRESS_ADDI_INSN. Make the M_LI_DD code fall through into the M_L_DAB code once the address has been constructed. For double load and store macros, again handle the 16-bit offset case first. If the second register cannot be accessed from the same high part as the first, load it into AT using ADDRESS_ADDI_INSN. Fix the handling of LD in cases where the first register is the same as the base. Also handle the case where the offset is not 16 bits and the second register cannot be accessed from the same high part as the first. For unaligned loads and stores, fuse the offbits == 12 and old "ab" handling. Apply this handling whenever the second offset needs a different high part from the first. Construct the offset using ADDRESS_ADDI_INSN where possible, for offbits == 16 as well as offbits == 12. Use offset_reloc when constructing the individual loads and stores. (mips_ip): Set up imm_expr, imm2_expr, offset_expr, imm_reloc and offset_reloc before matching against a particular opcode. Handle elided 'A' constants. Allow 'A' constants to use relocation operators. gas/testsuite/ * gas/mips/ldstla-32.d: Avoid "lui at,0x0" sequences for truncated constants. * gas/mips/ldstla-32-shared.d: Likewise. * gas/mips/mcu.d: Use ADDIU in preference to LI+ADDU when adding 16-bit constants to the base. * gas/mips/micromips@mcu.d: Likewise. * gas/mips/micromips@cache.d: Likewise. * gas/mips/micromips@pref.d: Likewise. * gas/mips/micromips.d, gas/mips/micromips-insn32.d, gas/mips/micromips-noinsn32.d, gas/mips/micromips-trap.d: Likewise. Allow the full 16-bit offset range to be used for SB, LB and LBU in USH and ULH sequences. Fix the expected output for LD and SD when the two LW and SW offsets need different high parts. * gas/mips/eva.s: Test PREFE with relocation operators. * gas/mips/eva.d: Use ADDIU in preference to LI+ADDU for 16-bit constants. Update after eva.s change. * gas/mips/micromips@eva.d: Likewise. * gas/mips/ld-reloc.s, gas/mips/ld-reloc.d, gas/mips/l_d-reloc.s, gas/mips/l_d-reloc.d, gas/mips/ulw-reloc.s, gas/mips/ulw-reloc.d, gas/mips/micromips@ulw-reloc.d, gas/mips/ulh-reloc.s, gas/mips/ulh-reloc.d: New tests. * gas/mips/mips.exp: Run them. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
