[Bug debug/14423] New: Missing debug_line info for non-inline function call site with inline call in parameter

[rdelashmit at soe dot sony dot com]

In the case shown below, a non-inline function call which has inline function 
calls in its parameter list does not generate debug_line information with gcc 
3.2.3.  debug_line information is generated when using gcc 2.95.3.

Compiler info, preprocessed source, and dwarfdump output follow.  The debug 
info does get generated by gcc 2.95.3 but not by gcc 3.2.3.

Looks to be fixed for both 3.3.1 and 3.4.0, can you try 3.3.3 and see if it is fixed?

is fixed?

I tried 3.3.3, and dwarfdump is identical to that given using 3.2.3.  I also 
built and tested a cvs version from yesterday (3.5.0 20040303 (experimental)) 
and the relevant debug info is missing there as well.  Below is the dwarfdump 
for the 3.3.3 built file, and the 2.95.3 built file.  Source lines 17 and 18 
are the ones I would expect to be present that are missing from the 3.x built 
file.

With 3.3.3:

dwarfdump can be found at http://reality.sgi.com/davea
'dwarfdump -l' output as I used previously is the equivalent of 'readelf -wl', 
so I'll switch to that format for consistency.

Using gcc 3.3.3 and readelf -wl, I don't get the same results that you did.

I get the following (once again missing source lines 17 and 18):

  Extended opcode 2: set Address to 0x0
  Advance Line by 10 to 11
  Copy
  Special opcode 48: advance Address by 3 to 0x3 and Line by 1 to 12
  Special opcode 118: advance Address by 8 to 0xb and Line by 1 to 13
  Special opcode 50: advance Address by 3 to 0xe and Line by 3 to 16
  Advance Line by -10 to 6
  Special opcode 131: advance Address by 9 to 0x17 and Line by 0 to 6
  Special opcode 144: advance Address by 10 to 0x21 and Line by -1 to 5
  Special opcode 174: advance Address by 12 to 0x2d and Line by 1 to 6
  Special opcode 144: advance Address by 10 to 0x37 and Line by -1 to 5
  Advance Line by 15 to 20
  Special opcode 173: advance Address by 12 to 0x43 and Line by 0 to 20
  Advance PC by 11 to 4e
  Extended opcode 1: End of Sequence

Okay, you had forgot to say that you were compiling with optimization.  Anyways this is fixed on the 
mainline by the merge of the tree-ssa so closing as fixed.
