operand specifiers. Change warning generated by 'B' operand
specifier to reflect its new multi-purpose usage.
+ * config/tc-mips.c (mips_set_options): Use ISA_UNKNOWN rather than
+ -1, and update comment.
+ (file_mips_isa): Likewise.
+ (mips_cpu): Use CPU_UNKNOWN rather than -1, and update comment.
+ (ISA_HAS_COPROC_DELAYS, ISA_HAS_64BIT_REGS, gpr_interlocks): Use
+ ISA_* constants rather than hard-coded numbers.
+ (mips_cpu_info): New structure.
+ (mips_cpu_info_table): New table describing CPU and ISA names
+ and numbers.
+ (mips_cpu_info_from_name, mips_cpu_info_from_isa,
+ mips_cpu_info_from_cpu): New functions.
+ (mips_isa_to_str): New function to get string for ISA name.
+ (mips_cpu_to_str): Convert to use mips_cpu_info_from_cpu, and
+ return const char *.
+ (md_begin): Redo CPU and ISA selection logic, using
+ mips_cpu_info_from_*. Convert to use ISA_* constants rather
+ than hard-coded numbers.
+ (append_insn, mips_emit_delays, macro, macro2): Convert to use
+ ISA_* constants rather than hard-coded numbers.
+ (mips_ip): Convert to use mips_isa_to_str to get ISA name.
+ (md_longopts): Delete OPTION_NO_MIPS32.
+ (md_parse_option): Convert to use ISA_* constants rather than
+ hard-coded numbers. Make OPTIONS_MIPS32 case treat MIPS32
+ as an ISA. Delete OPTION_NO_MIPS32 case. Convert OPTION_MCPU
+ to use strcasecmp to recognize "default" and to use
+ mips_cpu_info_from_name to get CPU numbers from argument.
+ (md_show_usage): Move -mips32 so it's with the rest of the ISA
+ flags. Change 4Kc, 4Kp and 4Km CPU entries to just be
+ mips32-4k.
+ (s_mipsset): Accept ISA value 32.
+ * doc/as.texinfo: Clean up MIPS options summary slightly,
+ remove -no-mips32. Add note about -mips4 and -mips32
+ specifying those ISA levels. Delete -mips32 and -no-mips32
+ cpu flag descriptions.
+ * doc/c-mips.texi: Add -mips32 to list of ISA switches. Clean
+ up the supported CPU switch list, and replace 4Kc, 4Km, and
+ 4Kp entries with a single mips32-4k entry. Note that you can
+ use ".set mips32".
