From 5ecc64bd129a0c4dfe4d4722c6e23968bc3011d0 Mon Sep 17 00:00:00 2001 From: Christophe Fergeau Date: Tue, 22 Mar 2011 17:05:43 +0100 Subject: common/gl: remove unused variable clang static analyzer warned that 'len' was computed but never used in glc_vertex2d. glc_stroke_line_dash has side effects so we have to call it, but we don't need to save its return value since it's not used. --- common/glc.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/common/glc.c b/common/glc.c index e4263cd4..e58718f1 100644 --- a/common/glc.c +++ b/common/glc.c @@ -1147,10 +1147,9 @@ static double glc_stroke_line_dash(double x1, double y1, double x2, double y2, static void glc_vertex2d(InternaCtx *ctx, double x, double y) { - double len; if (ctx->path_stroke.state == GLC_STROKE_ACTIVE) { - len = glc_stroke_line_dash(ctx->path_stroke.x, ctx->path_stroke.y, x, y, - ctx->line_width, &ctx->line_dash); + glc_stroke_line_dash(ctx->path_stroke.x, ctx->path_stroke.y, x, y, + ctx->line_width, &ctx->line_dash); ctx->path_stroke.x = x; ctx->path_stroke.y = y; } else if (ctx->path_stroke.state == GLC_STROKE_FIRST) { -- cgit v1.2.3
