[Bug c/25567] New: 4 * set but never used

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile the gcc-4.2 snapshot 20051224 with the Intel C
compiler. It said

1.

../../src/gcc-4.2-20051224/gcc/c-decl.c(4486): remark #593: variable
"type_as_written" was set but
never used

The source code is

    tree type_as_written;

I have read the source code, and I agree with the compiler.
The local variable is only ever written to. Suggest delete local variable.

2.

../../src/gcc-4.2-20051224/gcc/tree-cfg.c(3083): remark #593: variable "src"
was set but never used

The source code is

  basic_block new_bb, after_bb, dest, src;

More of the same.

3.

../../src/gcc-4.2-20051224/gcc/tree-outof-ssa.c(1843): remark #593: variable
"changed" was set but
never used

The source code is

  bool changed;

More of the same.

4.

../../src/gcc-4.2-20051224/gcc/tree-ssa-copy.c(352): remark #593: variable
"lhs" was set but never
used

The source code is

  tree lhs, rhs;

More of the same.
