From 50cdccf3efaa13dd11d1533b73fb34e0429d5cd6 Mon Sep 17 00:00:00 2001 From: seyko Date: Tue, 3 Mar 2015 14:19:14 +0300 Subject: Added a gcc preprocessor options -P, -P1 tcc -E -P do not output a #line directive, a gcc compatible option tcc -E -P1 don't follow a gcc preprocessor style and do output a standard #line directive. In such case we don't lose a location info when we going to compile a resulting file wtith a compiler not understanding a gnu style line info. --- libtcc.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'libtcc.c') diff --git a/libtcc.c b/libtcc.c index c68221e..3581ffb 100644 --- a/libtcc.c +++ b/libtcc.c @@ -1647,6 +1647,7 @@ enum { TCC_OPTION_I, TCC_OPTION_D, TCC_OPTION_U, + TCC_OPTION_P, TCC_OPTION_L, TCC_OPTION_B, TCC_OPTION_l, @@ -1695,6 +1696,7 @@ static const TCCOption tcc_options[] = { { "I", TCC_OPTION_I, TCC_OPTION_HAS_ARG }, { "D", TCC_OPTION_D, TCC_OPTION_HAS_ARG }, { "U", TCC_OPTION_U, TCC_OPTION_HAS_ARG }, + { "P", TCC_OPTION_P, TCC_OPTION_HAS_ARG | TCC_OPTION_NOSEP }, { "L", TCC_OPTION_L, TCC_OPTION_HAS_ARG }, { "B", TCC_OPTION_B, TCC_OPTION_HAS_ARG }, { "l", TCC_OPTION_l, TCC_OPTION_HAS_ARG | TCC_OPTION_NOSEP }, @@ -1930,6 +1932,9 @@ PUB_FUNC int tcc_parse_args(TCCState *s, int argc, char **argv) tcc_warning("-E: some compiler action already specified (%d)", s->output_type); s->output_type = TCC_OUTPUT_PREPROCESS; break; + case TCC_OPTION_P: + s->Pflag = atoi(optarg) + 1; + break; case TCC_OPTION_MD: s->gen_deps = 1; break; -- cgit v1.3.1
