[parisc-linux] binutils_2.14.90 bug

[John David Anglin]

Hi Grant,

Due to an "improvement" made for the detection of labels on ia64,
the PA assembler no longer tolerants whitespace in the operand field.
The only whitespace that is allowed is after `,'.  So, you need to
remove the whitespace around `+' and `*'.  If you look at the HP
assembler docs, you will see that they never show any whitespace
in the operands field.

Previously, the assembler used to strip the whitespace by default.
The reason that we can strip whitespace after `,' is that `,' never
ends an opcode.

This came up before on this list.
