Fix yet another gcc2 merge problem, this one broke linux kernel compiles
* loop.c (invariant_p, case MEM): Put MEM_VOLATILE_P check back.
From-SVN: r30496
* gcc/cp/init.c (init_init_processing): Header information for
arrays allocated via `new' should have the same alignment used by
malloc.
From-SVN: r30491
* flow.c (compute_flow_dominators): Initially put all blocks on
the worklist.
* lcm.c (compute_antinout_edge, compute_available): Similarly.
* gcse.c (compute_cprop_avinout): Remove.
(compute_cprop_data): Use compute_available.
(delete_null_pointer_checks_1): Use compute_available.
From-SVN: r30484
* basic-block.h (compute_available): Returns a void now.
* gcse.c (one_classic_gcse_pass): Do not expect compute_available
to return a value anymore.
* lcm.c (compute_available, compute_antinout_edge): Revamp to use
worklists. Fix boundary cases. Compute maximal solutions.
(compute_laterin, compute_nearerout): Similarly.
From-SVN: r30482
* gcov.c (struct arcdata): Add hits and total, remove prob.
(output_branch_counts): New.
(process_args): Set output_branch_counts if -c.
(calculate_branch_probs): Store hits and total instead of
percentage.
(output_data): Emit counts if output_branch_counts is true.
* gcov.texi (Invoking Gcov): Document -c switch..
From-SVN: r30476
* flow.c (compute_flow_dominators): No longer treat basic block 0
or (n_basic_blocks - 1) specially. Clear the AUX field before
starting computation of doms/pdoms. Fix initial state for pdoms.

* config/i386/xm-djgpp.h (HAVE_DOS_BASED_FILE_SYSTEM): Renamed
from HAVE_DOS_BASED_FILESYSTEM.
* gcc.c (find_a_file): Use HAVE_DOS_BASED_FILE_SYSTEM, not
HAVE_DOS_BASED_FILESYSTEM.
(main): Likewise.
(split_directories): Only special-case DOS file names if
HAVE_DOS_BASED_FILE_SYSTEM is defined. Use IS_DIR_SEPARATOR
instead of explicit tests. Conditionalize on !VMS.
(make_relative_prefix): Use IS_DIR_SEPARATOR instead of explicit
tests. Conditionalize on !VMS.
(process_command): Only use make_relative_prefix if !VMS.
(free_split_directories): Conditionalize on !VMS.
(DIR_UP): Conditionalize on !VMS.

* gcc.c (STANDARD_BINDIR_PREFIX): Provide default.
Fri Feb 5 14:22:01 1999 Mumit Khan <khan@xraylith.wisc.edu>
* gcc.c (make_relative_prefix): Handle the HAVE_EXECUTABLE_SUFFIX
case.
Mon Nov 8 14:16:57 1999 Michael Meissner <meissner@cygnus.com>
* invoke.texi (Environment Variables): Document relative path
lookup.
* gcc.c (DIR_UP): If not defined, define as "..".
(standard_bindir_prefix): New static, holds target location to
install binaries.
(split_directories): New function to split a filename into
component directories.
(free_split_directories): New function, release memory allocated
by split_directories.
(make_relative_prefix): New function, make a relative pathname if
the compiler is not in the expected location.
(process_command): If GCC_EXEC_PREFIX was not specified, see if we
can figure out an appropriate prefix from argv[0].
* Makefile.in (DRIVER_DEFINES): Use unlibsubdir in definition of
STANDARD_STARTFILE_PREFIX and TOOLDIR_BASE_PREFIX. Define
STANDARD_BINDIR_PREFIX.
From-SVN: r30464
* config/c4x/c4x-protos.h: New file. Prototypes for functions defined
in c4x.c.
* config/c4x/c4x.h: Moved prototypes to c4x.h.
* config/c4x/c4x.c (c4x_preferred_reload_class, c4x_limit_reload_class,
c4x_secondary_memory_needed) Delete.
(fp_zero_operand): Add mode argument.

that is in reload_reg_used.
