Hi,
I believe the number WN_Get_Linenum() returns is not directly the line num, it
includes both line number and file number, and you need to extract the linenum
using the srcpos interface in common/com/srcpos.h. I believe there is a way to
get the file name from the file number, but this file number will not be useful
in IPA, because it's based on pre-IPA file structure. There are other ways to
get it in IPA. Each IPA_NODE has a File_Id(), that will at least tell you if 2
functions belong to the same or different file. And see
IPA_Check_Optimization_Options() in ipa_cg.cxx that shows a way to retrieve the
original filename from the file header (see IP_FILE_HDR_file_name).

Subject: [Open64-devel] how we can get the filename and line number for a WHIRL
node?
Hi, all,
if I have the following statement, such as:
test.c
.
LINE:18 *p =2
for the above ISTORE node, how can I get the filename and line number
information, for line number,
in the common/com/wn_core.cxx, there is a function:
/*REFERENCED*/
inline INT64 WN_Get_Linenum(const WN *wn)
{
if (OPCODE_has_next_prev(WN_opcode(wn))) {
return WN_linenum(wn);
} else {
return 0;
}
}
but how about file name? is there a similar API I can use? intra-procedurally,
there is a global variable "Orig_Src_File_Name" I can use,
how about in IPA before the final transformation?
Thanks.
