Fix PR576.

Instead of emitting a JIT stub that looks like this:

internal void %l1_main_entry_2E_ce_wrapper(int) {
header:
        %resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) )           ; <sbyte*> [#uses=1]
        %resolverCast = cast sbyte* %resolver to void (int)*            ; <void (int)*> [#uses=1]
        call void %resolverCast( int %0 )
        ret void
}

Emit one that looks like this:

internal void %l1_main_entry_2E_ce_wrapper(int) {
Entry:
%fpcache = load void (int)** %l1_main_entry_2E_ce.fpcache               ; <void (int)*> [#uses=2]
        %isNull = seteq void (int)* %fpcache, null              ; <bool> [#uses=1]
        br bool %isNull, label %lookupfp, label %usecache

usecache:               ; preds = %lookupfp, %Entry
        %fp = phi void (int)* [ %resolverCast, %lookupfp ], [ %fpcache, %Entry ]            ; <void (int)*> [#uses=1]
        call void %fp( int %0 )
        ret void

lookupfp:               ; preds = %Entry
        %resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) )           ; <sbyte*> [#uses=1]
        %resolverCast = cast sbyte* %resolver to void (int)*            ; <void (int)*> [#uses=2]
        store void (int)* %resolverCast, void (int)** %l1_main_entry_2E_ce.fpcache
        br label %usecache
}

This makes the JIT debugger *MUCH* faster on large programs, as
getPointerToNamedFunction takes time linear with the size of the program, and
before we would call it every time a function in the text module was called from
the safe module (ouch!).

Final Changes For PR495:

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:

makeReadable        -> makeReadableOnDisk
makeWriteable       -> makeWriteableOnDisk
makeExecutable      -> makeExecutableOnDisk
setStatusInfo       -> setStatusInfoOnDisk
createDirectory     -> createDirectoryOnDisk

19 years agoFirst round of support for doing scalar FP using the SSE2 ISA extension and
Nate Begeman [Wed, 6 Jul 2005 18:59:04 +0000 (18:59 +0000)]
First round of support for doing scalar FP using the SSE2 ISA extension and
XMM registers.  There are many known deficiencies and fixmes, which will be
addressed ASAP.  The major benefit of this work is that it will allow the
LLVM register allocator to allocate FP registers across basic blocks.

The x86 backend will still default to x87 style FP.  To enable this work,
you must pass -enable-sse-scalar-fp and either -sse2 or -sse3 to llc.

An example before and after would be for:
double foo(double *P) { double Sum = 0; int i; for (i = 0; i < 1000; ++i)
                        Sum += P[i]; return Sum; }

The inner loop looks like the following:
x87:
.LBB_foo_1:     # no_exit
        fldl (%esp)
        faddl (%eax,%ecx,8)
        fstpl (%esp)
        incl %ecx
        cmpl $1000, %ecx
        #FP_REG_KILL
        jne .LBB_foo_1  # no_exit

SSE2:
        addsd (%eax,%ecx,8), %xmm0
        incl %ecx
        cmpl $1000, %ecx
        #FP_REG_KILL
        jne .LBB_foo_1  # no_exit

Initial set of .td file changes necessary to get scalar fp in xmm registers
working.  The instruction selector changes will hopefully be coming later
this week once they are debugged.  This is necessary to support the darwin
x86 FP model, and is recommended by intel as the replacement for x87.  As
a bonus, the register allocator knows how to deal with these registers
across basic blocks, unliky the FP stackifier.  This leads to significantly
better codegen in several cases.
