[Bug c/26245] New: 10 * local variable set but not used

[dcb314 at hotmail dot com]

I just tried to compile the GNU CC version 4.2 snapshot 20060211 with
the Intel C compiler.

It said

../../src/gcc-4.2-20060211/gcc/c-decl.c(4523): remark #593: variable
"type_as_written" was set but never used
../../src/gcc-4.2-20060211/gcc/tree-cfg.c(3207): remark #593: variable "src"
was set but never used
../../src/gcc-4.2-20060211/gcc/tree-dfa.c(732): remark #593: variable "v_ann"
was set but never used
../../src/gcc-4.2-20060211/gcc/tree-into-ssa.c(1441): remark #593: variable
"ann" was set but never
used
../../src/gcc-4.2-20060211/gcc/tree-outof-ssa.c(1892): remark #593: variable

../../src/gcc-4.2-20060211/gcc/tree-outof-ssa.c(1843): remark #593: variable

../../src/gcc-4.2-20060211/gcc/tree-ssa-copy.c(674): remark #593: variable
"ann" was set but never used
../../src/gcc-4.2-20060211/gcc/tree-ssa-operands.c(957): remark #593: variable
"ann" was set but never used
../../src/gcc-4.2-20060211/gcc/tree-ssa-alias.c(1430): remark #593: variable
"n_vars" was set but never used

I've checked all of these, and they all look like local variable that can
safely
be deleted to me.

Thanks for the report. I think all these have been fixed already in GCC 4.6 and
regressions would be detected by the new -Wunused-but-set flags.
