* fhandler.h: Declare new function. Add extra argument to
process_slave_output.
* fhandler_console.cc (fhandler_console::read): Move read ahead code to new
function.

here.
(fhandler_tty_slave::read): Understand readahead.
(fhandler_pty_master::read): Move code to process_slave_output.
* select.cc (peek_pipe): Avoid performing certain checks when non-read and on
inappropriate fh types.
on interrupt if executing in a "cygwin" thread.
* fhandler_tty.cc (fhandler_pty_master::process_slave_output): Streamline,
simplify code.
* sigproc.cc (sig_send): Remove debugging statement.
* elf32-mips.c (mips_elf_next_relocation): Rename from
mips_elf_next_lo16_relocation, and generalize to look
for any relocation type.
(elf_mips_howto_table): Make R_MIPS_PC16 pcrel_offset.
(elf_mips_gnu_rel_hi16): Howto for R_MIPS_GNU_REL_HI16.
(elf_mips_gnu_rel_lo16): Howto for R_MIPS_GNU_REL_LO16.
(elf_mips_gnu_rel16_s2): Howto for R_MIPS_GNU_REL16_S2.
(elf_mips_gnu_pcrel64): Howto for R_MIPS_PC64.
(elf_mips_gnu_pcrel32): Howto for R_MIPS_PC32.
(bfd_elf32_bfd_reloc_type_lookup): Add new relocs.
(mips_rtype_to_howto): Likewise.
(mips_elf_calculate_relocation): Handle new relocs.
(_bfd_mips_elf_relocate_section): REL_HI16/REL_LO16 relocs
are paired. The addend for R_MIPS_GNU_REL16_S2
is shifted right two bits.
In gas/:
* config/tc-mips.c (mips_ip): Don't put stuff in .rodata
when embedded-pic.
* config/tc-mips.c (SWITCH_TABLE): The ELF embedded-pic
implementation doesn't have special handling for switch
statements.
(macro_build): Allow for code in sections other than .text.
(macro): Likewise.
(mips_ip): Likewise.
(md_apply_fix): Do pc-relative relocation madness for MIPS ELF.
Don't perform relocs if we will be outputting them.
(tc_gen_reloc): For ELF, just use fx_addnumber for pc-relative
relocations. Allow BFD_RELOC_16_PCREL_S2 relocs when
embedded-pic.
In gas/testsuite/:
* gas/mips/empic.d: New file.
* gas/mips/empic.s: New file.
* gas/mips/mips16-e.d: New file.
* gas/mips/mips16-e.s: New file.
* gas/mips/mips16-f.d: New file.
* gas/mips/mips16-f.s: New file.
* gas/mips/mips.exp: Add empic, mips16-e. Add mips16-f as an
expected failure.
In include/elf:
* mips.h: Add R_MIPS_GNU_REL_HI16, R_MIPS_GNU_REL_LO16,
R_MIPS_GNU_REL16_S2, R_MIPS_PC64 and R_MIPS_PC32 relocation
numbers.
* libc/include/string.h: Changed last argument back to ssize_t
to make it compatible with XPG4 definition which is
defined in <unistd.h>. There is a conflict in the SVID 3
and XPG4 definitions and newlib will settle with XPG4.
* libc/string/swab.c: Ditto.
* exceptions.cc (sfta): Eliminate obsolete function.
(sgmb): Eliminate obsolete function.
(class stack_info): Remove MS method for walking the stack.
(stack_info::init): Just initialize required fields.
(stack_info::brute_force): Rename to stack_info::walk.
(handle_exceptions): Pass derived frame pointer to sig_send.
(interrupt_setup): Clear saved frame pointer here.
(interrupt_on_return): thestack is no longer a pointer.
(call_handler): Accept a flag to indicate when a signal was sent from other
than the main thread. Use saved frame pointer for determining where to place
signal handler call.
(sig_handle): Accept "nonmain" argument. Pass it to call_handler.
* fhandler_tty.cc (fhandler_tty_common::__acquire_output_mutex): Change
debugging output slightly.
* (fhandler_tty_common::__release_output_mutex): Ditto.
(fhandler_tty_slave::read): Fix a comment, remove a goto.
* sigproc.cc (sig_send): Accept an optional frame pointer argument for use when
suspending the main process. sigcomplete_main is an autoreset event now. Save
frame pointer for non-main operation.
(wait_sig): Make sigcomplete_main an autoreset event. Eliminate NOSIGQUEUE.
Pass rc to sig_handle to signify if this was a nonmain process.
* sigproc.h: Reflect change to sig_send argument.
* syscalls.cc (swab): Eliminate swab function since it is now available in
newlib.
* winsup.h (signal_dispatch): Change CONTEXT cx to DWORD ebp.
(CHEWOUT_FILES): Added getw.def and putw.def.
* libc/stdio/Makefile.in: Rebuilt.
* libc/stdio/stdio.tex: Include getw.def and putw.def.
* libc/stdio/getw.c: New file.
* libc/stdio/putw.c: New file.
Patches from Jan Nijtmans <j.nijtmans@chello.nl>:
* include/wtypes.h (PBLOB, LPBLOB): Define.
* include/winsock2.h: Much more complete version.
(FD_SET, SOMAXCONN): Protect common macros defined by winsock.h.
* include/winbase.h (TLS_MINIMUM_AVAILABLE): Move macro from here
* include/winnt.h (TLS_MINIMUM_AVAILABLE): to here.
(NT_TIB): Define.
* include/tlhelp32.h: New file.
(getprogname): Eliminate obsolete function.
(dll_crt0_1): Move initial strace initialization output to set_myself.
* exceptions.cc (interruptible): Add debugging output.
(interrupt_setup): New function.
(interrupt_now): Use interrupt_setup to set up common interrupt handler stuff.
(interrupt_on_return): Ditto.
(call_handler): Move signal_arrived arm and clear threads to region where
signalled thread is suspended or suffer races.
* pinfo.cc (set_myself): Output interesting information when strace is first
initialized. Initialize progname here.
* sigproc.cc (sig_dispatch_pending): Modify to ensure that flush signal are
sent synchronously.
* strace.cc (strace_vsprintf): Move code into strace program.
* uname.cc (uname): Use 'osname' global to construct cygwin name + Windows type
+ version.
(call_handler): Allow signals to be sent even if signalled thread is stopped.
Change order of signal_arrived arming/waiting threads clearing to eliminate a
race.
(reset_signal_arrived): New helper function.
* malloc.cc (malloc_init): Use mutos so that signal handler can keep track of
who owns the lock.
(__malloc_lock): Ditto.
(__malloc_unlock): Ditto.
* sync.h (new_muto): Actually use a muto for the "buffer".
* Makefile.in: Fix a dependency.
the errors exposed by this addition. These were intel mode
"fi... word ptr", "fi... dword ptr", "jmp Imm seg, Imm offset", "out dx,al".
The failure with intel "out dx,al" was also present in att "out al,dx".
Extend testsuite to catch this case too.
