Hi,
I dumped when I debug the whirl2c procedure in function preprocess_pu, just
after it has read the Whirl tree from *.B file.
When exit the gdb pthread, the binded thread will print the whirl tree.

I suspect you dumped the symtab is unavailable. Where did you do the dump?

Hi,
I encounter a error in Open64 whirl2c Phase, the phenomena is as follow:
when loaded pu in Preprocess_pu, dump_tree(pu), there are some NULL WN in
the whirl tree, such as:
MCALL 64 <1,94,UPCR_ADD_SHARED_MD> # flags 0x40 add_shared1
MMLDID -1 <null-st> T<43,shared_ptr_struct,4>
U4LDA 0 <3,39,_bupc_.Mptra.> T<136,anon_ptr.,4>
U4INTCONST 8 (0x8)
MLOAD 0 T<137,anon_ptr.,4>
U4TAS T<111,anon_ptr.,4>
MPARM 2 T<43,shared_ptr_struct,4> # by_value
I4INTCONST 4 (0x4)
I4PARM 2 T<### ERROR: null ptr> # by_value
I4I4LDID 0 <3,10,__HL_j> T<58,int,4>
I4PARM 2 T<### ERROR: null ptr> # by_value
U4LDA 0 <1,86,input_mdl> T<127,anon_ptr.,4>
MPARM 2 T<45,mdl_ptr_struct,4> # by_value
I4INTCONST 0 (0x0)
I4PARM 2 T<4,.predef_I4,4> # by_value
MCALL 64 <1,94,UPCR_ADD_SHARED_MD> # flags 0x40
at the same time, I get the correspond WN in Backend_processing as follow:
F4CALL 126 <1,96,UPCR_GET_SHARED_FLOATVAL> # flags 0x7e
F4F4LDID 8 <1,80,.preg_I8> T<10,.predef_F4,4> # $r8
F4STID 0 <3,20,_bupc_.spillld> T<10,.predef_F4,4>
U4LDA 0 <3,39,_bupc_.Mptra.> T<136,anon_ptr.,4>
U4INTCONST 8 (0x8)
MLOAD 0 T<137,anon_ptr.,4>
U4TAS T<111,anon_ptr.,4>
MPARM 2 T<43,shared_ptr_struct,4> # by_value
I4INTCONST 4 (0x4)
I4PARM 2 T<4,.predef_I4,4> # by_value
I4I4LDID 0 <3,10,__HL_j> T<58,int,4>
I4PARM 2 T<4,.predef_I4,4> # by_value
U4LDA 0 <1,86,input_mdl> T<127,anon_ptr.,4>
MPARM 2 T<45,mdl_ptr_struct,4> # by_value
I4INTCONST 0 (0x0)
I4PARM 2 T<4,.predef_I4,4> # by_value
MCALL 64 <1,94,UPCR_ADD_SHARED_MD> # flags 0x40
Are there some advice about it? Can it be a error during loading the WN in
the whirl2c phase?
Thanks in advance!
Eric
