@ifset CRIS
See the info pages for documentation of the CRIS-specific options.
Cause nops to be inserted if a dmult or dmultu instruction is
followed by a load instruction.
+@item -mfix-r5900
+@itemx -mno-fix-r5900
+Do not attempt to schedule the preceding instruction into the delay slot
+of a branch instruction placed at the end of a short loop of six
+instructions or fewer and always schedule a @code{nop} instruction there
+instead. The short loop bug under certain conditions causes loops to
+execute only once or twice, due to a hardware bug in the R5900 chip.
+
@item -mdebug
@itemx -no-mdebug
Cause stabs-style debugging output to go into an ECOFF-style .mdebug
instructions.
@samp{-mno-loongson-mmi} turns off this option.
+@item -mloongson-cam
+@itemx -mno-loongson-cam
+Generate code for the Loongson Content Address Memory (CAM) instructions.
+This tells the assembler to accept Loongson CAM instructions.
+@samp{-mno-loongson-cam} turns off this option.
+
+@item -mloongson-ext
+@itemx -mno-loongson-ext
+Generate code for the Loongson EXTensions (EXT) instructions.
+This tells the assembler to accept Loongson EXT instructions.
+@samp{-mno-loongson-ext} turns off this option.
+
+@item -mloongson-ext2
+@itemx -mno-loongson-ext2
+Generate code for the Loongson EXTensions R2 (EXT2) instructions.
+This option implies @samp{-mloongson-ext}.
+This tells the assembler to accept Loongson EXT2 instructions.
+@samp{-mno-loongson-ext2} turns off this option.

@item -minsn32
@itemx -mno-insn32
Only use 32-bit instruction encodings when generating code for the
strongarm, it is the
number of low-order zero bits the location counter must have after
advancement. For example @samp{.align 3} advances the location
-counter until it a multiple of 8. If the location counter is already a
+counter until it is a multiple of 8. If the location counter is already a
multiple of 8, no change is needed.
This inconsistency is due to the different behaviors of the various
storage boundary. The first expression (which must be absolute) is the
number of low-order zero bits the location counter must have after
advancement. For example @samp{.p2align 3} advances the location
-counter until it a multiple of 8. If the location counter is already a
+counter until it is a multiple of 8. If the location counter is already a
multiple of 8, no change is needed.
The second expression (also absolute) gives the fill value to be stored in the
@end table
+Changing between incompatible types other than from/to STT_NOTYPE will
+result in a diagnostic. An intermediate change to STT_NOTYPE will silence
+this.
+
Note: Some targets support extra types in addition to those listed above.

@cindex filling memory with zero bytes
This directive emits @var{size} 0-valued bytes. @var{size} must be an absolute
expression. This directive is actually an alias for the @samp{.skip} directive
-so in can take an optional second argument of the value to store in the bytes
+so it can take an optional second argument of the value to store in the bytes
instead of zero. Using @samp{.zero} in this way would be confusing however.
