[Open64-devel] Compiler fails because of an undefined symbol

[Marc Gonzalez-S. <mar...@in...>]

Hello all,

I run native ORC 2.1 on an Itanium 1 (I installed the binary 
distribution).

I wrote a naive matrix multiply program (see attached file) so I 
could see the result of the LNO phase. I intended to use whirl2c on 
the optimized intermediate representation.

However, when I set preopt and lno to ON, and wopt and cg to OFF, 
the compiler fails:

$ orcc -keep -PHASE:p=on:l=on:w=off:c=off matrix.c

whirl2c works with matrix.B but not with matrix.N and, as far as I 
can tell, matrix.B is generated before LNO.

$ whirl2c matrix.B

I found references to TI_RES_COUNT_Alloc inside cg.so, lno.so and 
orc_intel.so (apparently it is defined in cg.so).

cg.so:
00000000000a1470 g  F .text  0000000000000130    TI_RES_COUNT_Alloc
lno.so:
0000000000000000      *UND*  0000000000000000    TI_RES_COUNT_Alloc
orc_intel.so:
0000000000000000    F *UND*  0000000000000130    TI_RES_COUNT_Alloc

If I include the code generation phase, then the error message 
disappears, but matrix.N is not generated.

What is the problem?
