           Summary: [MC assembler] 'b' suffix on 'setxx' mnemonics not
                    accepted
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

In some contributed math library code in FreeBSD, there is the following
assembly instruction:

    setneb    %al

The 'b' suffix is not accepted by the MC assembler.  I know it is quite
redundant, but gas is the standard, unfortunately. :)

In binutils's i386 opcode table file, there is this fragment:

setne, 1, 0xf95, 0x0, 2, Cpu386,
Modrm|No_wSuf|No_lSuf|No_sSuf|No_qSuf|No_ldSuf, {
Reg8|Byte|Unspecified|BaseIndex|Disp8|Disp16|Disp32|Disp32S }

E.g. it accepts the 'b' suffix, but not the w, l, s, q, ld suffixes.
The same holds for all the following mnemonics:

seta
setae
setb
setbe
setc
sete
setg
setge
setl
setle
setna
setnae
setnb
setnbe
setnc
setne
setng
setnge
setnl
setnle
setno
setnp
setns
setnz
seto
setp
setpe
setpo
sets
setz
