           Summary: arm.c: 5 * set but not used
           Product: gcc

            Status: UNCONFIRMED
          Severity: minor
          Priority: P3

  Target Milestone: ---

1.

[trunk/gcc/config/arm/arm.c:14167]: (style) Variable 'base_reg' is assigned a
value that is never used.

Possible candidate for deletion.

2.

[trunk/gcc/config/arm/arm.c:14723]: (style) Variable 'i' is assigned a value
that is never used.

Strange looking for loop. Maybe rewrite it ?

3.

[trunk/gcc/config/arm/arm.c:21716]: (style) Variable 'insn' is assigned a value
that is never used.

Not sure if the instruction should be used someplace later.

4.

[trunk/gcc/config/arm/arm.c:23772]: (style) Variable 'pushed_words' is assigned
a value that is never used.

Candidate for deletion.

5.

[trunk/gcc/config/arm/arm.c:24059]: (style) Variable 'regs_to_pop' is assigned
a value that is never used.

The code that uses the variable is in a comment. Suggest either reinstate
the commented out code or remove the variable.
