I just tried to compile the gcc-4.2 snapshot 20051217 with the Intel C
compiler. It said
1.
../../src/gcc-4.2-20051217/gcc/builtins.c(1155): remark #593: variable
"apply_args_reg_offset" was
set but never used
The source code is
static int apply_args_reg_offset[FIRST_PSEUDO_REGISTER];
I have read the source code, and I agree with the compiler.
The data is only ever written to. Suggest delete dead data.
2.
../../src/gcc-4.2-20051217/gcc/gcse.c(290): remark #593: variable
"debug_stderr" was set but never
used
The source code is
static FILE *debug_stderr;
I have read the source code, and I agree with the compiler.
The data is only ever written to. Suggest delete dead data.
3.
../../src/gcc-4.2-20051217/gcc/ggc-common.c(68): remark #593: variable
"ggc_stats" was set but never used
The source code is
static ggc_statistics *ggc_stats;
I have read the source code, and I agree with the compiler.
The data is only ever written to. Suggest delete dead data.
