* flags.h (warn_padded, warn_packed): Add global var decls.
* toplev.c (warn_padded, warn_packed): Add global var defns.
(W_options): Add warnings `-Wpacked' and `-Wpadded'.
* stor-layout.c (layout_record): Add local variable `type'
to hold often-used TREE_TYPE (field). Add local variable
`unpacked_align' to hold alignment that would be in force
if no `packed' attribute were present. Warn if `packed' attribute
is unnecessary, or even harmful. Warn when gcc inserts padding
to satisfy alignment requirements of members. Use NULL_TREE
when checking whether var_size is set.
* invoke.texi: Document new flags.

* cccp.c (argdata): Added free_ptr member.
(macroexpand): Initialize free_ptr of each argument. When an
argument's buffers are freed, if the argument's free_ptr corresponds
to a buffer on the input stack, then return the free_ptr to that stack
frame, otherwise, free it.
(macarg): If an argument begins and ends on the same input stack level,
then transfer the free_ptr of that buffer to the argument in case
the stack is popped during the processing of a subsequent argument.

interface if bindAddr is null.
From-SVN: r30755
* config/sparc/sparc.md (movsf_const_intreg): Add constraints for
regclass' sake.
(movdf_const_intreg_sp32): Likewise. Prefer the memory load
alternative because setting up 64bit constant is usually costly,
especially when reload is in progress or completed.
(movdf_const_intreg_sp64): Likewise.
(movdf_const_intreg split): Fix building up constants when
HOST_BITS_PER_WIDE_INT is 64 yet long is 32bit.

const1_rtx for return values in EQ/NE comparison against (const_int 0)
case.

right.
Oh, and test the PR system. PR other/4.
From-SVN: r30737
* c-lex.c (yylex): With -Wtraditional, when the ANSI type of an
integer constant does not match the traditional type, limit the
warnings to cases where the base of the type is ten.
* invoke.texi (-Wtraditional): Document it.
From-SVN: r30730
* lcm.c (compute_laterin): Cast bb->aux to size_t not int.

size_t to unsigned long for formatting.
From-SVN: r30728
* config/sparc/sparc.h (FIXED_REGISTERS, CONDITIONAL_REGISTER_USAGE):
Allow the user to override call-used/fixed state of %g2-5
registers from the command line (with the exception of %g4 for
embedded model).
(REG_LEAF_ALLOC_ORDER): Move %g1 and %g4-7 registers to front, so that
there is a higher chance of having a leaf function.
(MACHINE_STATE_SAVE, MACHINE_STATE_RESTORE): Provide separate macros
for ARCH64 which has %ccr register.
* config/sparc/sparc.md (return_losum_si, return_losum_di): New
patterns.
* config/sparc/sparc.c (eligible_for_epilogue_delay): For the return
insn accept into delay slot any insn which does not use %[ol]
registers. Accept some LO_SUM and shift left by 1 for the normal
restore case.
(output_function_epilogue): Likewise.
(epilogue_renumber): Added argument which inhibits any renumbering
and just tests if the rtx does not use any %[ol] registers.
(output_return): Reflect above change.
From-SVN: r30727
* posix-threads.cc (_Jv_MutexInit): Use _Jv_PthreadGetMutex to get
mutex to initialize. Initialize `count' if required.
Fixes PR libgcj/98.
