X-Git-Tag: v0.5.0rc2~5^2~51
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=faee015579cb9b6175e42fd2958ca0a67e3aaffd;p=yasm

Remove some unused variables/functions.

* dwarf2-info.c (dwarf2_info_head_*): Remove.

* dwarf2-line.c (dwarf2_spp_bc_tobytes): Remove unused variable.
* dwarf2-dbgfmt.c (dwarf2_dbgfmt_generate, dwarf2_head_bc_tobytes): Likewise.
