So it seems fine within the object file itself, but if I > disassemble the final cc1 executable, it's become the invalid address: >> 06d777a0 <_ZN15variable_hasher6removeEP8variable>: >> 6d777a0: 00 10 19 0a 80 05 [MII] alloc r34=ar.pfs,6,5,0 >> 6d777a6: 30 02 30 00 42 80 mov r35=r12 >> 6d777ac: 01 67 fc 8c adds r12=-16,r12 >> 6d777b0: 01 00 00 00 01 00 [MII] nop.m 0x0 >> 6d777b6: 10 02 00 62 00 80 mov r33=b0 >> 6d777bc: 04 08 00 84 mov r36=r1;; >> 6d777c0: 18 00 80 46 90 11 [MMB] st4 [r35]=r32 >> 6d777c6: 50 02 8c 20 20 00 ld4 r37=[r35] >> 6d777cc: d8 96 cf 50 br.call.sptk.many >> b0=7a70e90 <_etext_f+0xc87090> > According to the cc1 symbol table, variable_htab_free should be at 0x5a70e90. > Which I just realized is exactly 0x2000000 off the invalid address... Okay, this is problem linkonce sections. I think we need to figure out why ia64_hpux_function_section isn't working. Maybe try return text_section in ia64_hpux_function_section.
