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. -- Summary: 4 * set but never used Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: dcb314 at hotmail dot com GCC host triplet: x86_64-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25567 ^ permalink raw reply [flat|nested] 5+ messages in thread
