@ -6,52 +6,153 @@ from Alexandre Oliva <aoliva@redhat.com>
(i386_linux_set_debug_regs_for_thread): ... this, and
add new function to catch exceptions in the old one.
Index: gdb-6.5/gdb/i386-linux-nat.c
2008-02-24 Jan Kratochvil <jan.kratochvil@redhat.com>
Port to GDB-6.8pre.
This patch was originally made to workaround a deficiency of ia32el (==ia32
emulator on ia64) which EIOs on ptrace(2) of the debug registers.
Currently I can no longer run gdb.i386 on RHEL-5.1.ia64 as it fails on
$ rpm -qv kernel

ia32-on-ia64 run problem info:
the inconsistency is in function linux_nat_wait - there is a variable called
block_mask, which is assumed to represent the current signal mask. in the
following execution path this assumption does not hold:
1) block-mask is filled with SIGCHLD and the signal is masked in
lin_lwp_attach_lwp, which is called at the beginning of the procedure
that handles a new thread in the debuggee.
2) further down this procedure gdb tries to set the debug regs of the debuggee.
when trying to set debug regs - gdb fails and calls throw_exception. this
function finishes with siglongjmp, which clears the sigmask (seq. 1).
3) further down, linux_nat_wait is called to wait on the new child. in
linux_nat_wait there is a sequence :
if ( ! (block_mask & SIGCHLD) )
mask- SIGCHLD
while () {
wait-no-hang( )
if no child found then
sigsuspend (SIGCHLD)
4) the signal that notifies the debugger about the child is received after the
wait and before the sigsuspend. originally, this was not supposed to happen
because SIGCHLD is supposed to be blocked, but because what happens in step
2, the signal mask is cleared and the signal is received at this point,
which results with a hang

2007-04-20 Luis Machado <luisgpm@br.ibm.com>
* rs6000-tdep.c (rs6000_gdbarch_init): Set the long double format for
powerpc64.
* configure.host : Set the host long double format for powerpc64 to be
a 128-bit type defined in libiberty/floatformat.c.
* ppc-linux-tdep.c (ppc_linux_init_abi): Remove code that sets long double
size to 8 bytes. This breaks expression evaluation by overriding the
default.
* floatformat.c : Introduce default floatformat structs to describe the
128-bit long double found on the powerpc64. Description does not fully
describe this format which is actually a pair of 64-bit doubles. However
we are relying on floatformat_to_doublest() recognizing that this is
also the default host floatformat.
* floatformat.h : Default floatformat structs for powerpc64 128-bit
long doubles.
