From 2aa12fbec81d02258178f259e0685c64d481d925 Mon Sep 17 00:00:00 2001 From: Nick Clifton Date: Fri, 5 May 2006 16:55:28 +0000 Subject: PR gas/2582 * dwarf2dbg.c (INSERT_DIR_SEPARATOR): New macro. Handles the insertion of a directory separator character into a string at a given offset. Uses heuristics to decide when to use a backslash character rather than a forward-slash character. (dwarf2_directive_loc): Use the macro. (out_debug_info): Likewise. --- gas/dwarf2dbg.c | 27 +++++++++++++++++++++++++-- 1 file changed, 25 insertions(+), 2 deletions(-) (limited to 'gas/dwarf2dbg.c') diff --git a/gas/dwarf2dbg.c b/gas/dwarf2dbg.c index 661962ff20..65a0a26696 100644 --- a/gas/dwarf2dbg.c +++ b/gas/dwarf2dbg.c @@ -46,6 +46,29 @@ #include "dwarf2dbg.h" #include +#ifdef HAVE_DOS_BASED_FILE_SYSTEM +/* We need to decide which character to use as a directory separator. + Just because HAVE_DOS_BASED_FILE_SYSTEM is defined, it does not + necessarily mean that the backslash character is the one to use. + Some environments, eg Cygwin, can support both naming conventions. + So we use the heuristic that we only need to use the backslash if + the path is an absolute path starting with a DOS style drive + selector. eg C: or D: */ +# define INSERT_DIR_SEPARATOR(string, offset) \ + do \ + { \ + if (offset > 1 \ + && string[0] != 0 \ + && string[1] == ':') \ + string [offset] = '\\'; \ + else \ + string [offset] = '/'; \ + } \ + while (0) +#else +# define INSERT_DIR_SEPARATOR(string, offset) string[offset] = '/' +#endif + #ifndef DWARF2_FORMAT # define DWARF2_FORMAT() dwarf2_format_32bit #endif @@ -569,7 +592,7 @@ dwarf2_directive_loc (int dummy ATTRIBUTE_UNUSED) char *cp = (char *) alloca (dir_len + 1 + file_len + 1); memcpy (cp, dirs[files[filenum].dir], dir_len); - cp[dir_len] = '/'; + INSERT_DIR_SEPARATOR (cp, dir_len); memcpy (cp + dir_len + 1, files[filenum].filename, file_len); cp[dir_len + file_len + 1] = '\0'; listing_source_file (cp); @@ -1464,7 +1487,7 @@ out_debug_info (segT info_seg, segT abbrev_seg, segT line_seg) len = strlen (dirs[files[1].dir]); p = frag_more (len + 1); memcpy (p, dirs[files[1].dir], len); - p[len] = '/'; + INSERT_DIR_SEPARATOR (p, len); } len = strlen (files[1].filename) + 1; p = frag_more (len); -- cgit v1.2.1
