Thanks.

Why doesn't _IO_getc get a stub on mips64, like say _setjmp?

readelf -a saved_ansi_gcl |grep  IO_getc
  2812: 0000000000000000   472 FUNC    GLOBAL DEFAULT  UND address@hidden (2)
 15315: 0000000000000000   472 FUNC    GLOBAL DEFAULT  UND _IO_getc@@GLIBC_2.0
readelf -a saved_ansi_gcl |grep  setjmp
  2159: 00000001204b9b40    32 FUNC    GLOBAL DEFAULT  UND address@hidden (2)
 15978: 00000001204b9b40    32 FUNC    GLOBAL DEFAULT  UND _setjmp@@GLIBC_2.0
 
Is there anything I can do about this?

Take care,
