=================================================================== 2007-02-01 Murali Vemulapati murali.vemulapati@gmail.com

  * config/i386/i386.h : define TARGET_CYGMING to 0.
  * config/i386/cygming.h : define TARGET_CYGMING to 1.
  Do not ignore -fpic.
  Declare i386_pe_generate_imported_symbol_ref().
  * config/i386/winnt.c : define function
  i386_pe_generate_imported_symbol_ref.
  * config/i386/i386.c : declare pic_base_label.
  (output_set_got): generate a base label and save it in pic_base_label.
  (legitimate_pic_address_disp_p) : UNSPEC_GOTOFF is generated for
  imported symbols too.
  (legitimize_pic_address) : generate UNSPEC_GOTOFF for dllimported
  and global symbols.
  (output_pic_addr_const) : On target cygming, interpret UNSPEC_GOTOFF
  as offset from base label.
  (imported_symbolic_operand): New function which returns true
  if operand is a symbol rtx and is dllimported.
  (ix86_output_addr_diff_elt) : output an element of address diff
  vector as a relative offset from base label.
  (ix86_expand_call) : On target cygming, convert the address of a
  non-static, direct function to a PIC reference by calling
  legitimize_pic_address.

From Murali Vemulapati Sent: Friday, 9 February 2007 7:36 a.m. Can somebody please review and/or approve this patch for i386/cygwin?

Thanks Murali

The patch does not apply cleanly. Most (all?) of the empty lines have been converted to two empty lines. Could you check that and perhaps resend as attachment rather than inline text.

Thanks Danny
