Message-ID: <200503082258.j28MwmRE002419@apoc.cs.uiuc.edu>



Changes in directory llvm-test:

Makefile.tests updated: 1.4 -> 1.5
Makefile.rules updated: 1.7 -> 1.8
---
Log message:

Turn off warnings for programs in llvm-test.  We are aware of the fact that
they are gross and crufty, they should not need to match the standards of the
main LLVM codebase.

Changes in directory llvm/lib/CodeGen/SelectionDAG:

SelectionDAG.cpp updated: 1.51 -> 1.52
---
Log message:

constant fold FP_ROUND_INREG, ZERO_EXTEND_INREG, and SIGN_EXTEND_INREG

This allows the alpha backend to compile:

bool %test(uint %P) {
        %c = seteq uint %P, 0
        ret bool %c
}

into:

test:
        ldgp $29, 0($27)
        ZAP $16,240,$0
        CMPEQ $0,0,$0
        AND $0,1,$0
        ret $31,($26),1

instead of:

test:
        ldgp $29, 0($27)
        ZAP $16,240,$0
        ldiq $1,0
        ZAP $1,240,$1
        CMPEQ $0,$1,$0
        AND $0,1,$0
        ret $31,($26),1

	LiveIntervalAnalysis.h 
Message-ID: <200503092305.j29N5ZRk029965@apoc.cs.uiuc.edu>



Changes in directory llvm/lib/CodeGen:

LiveIntervalAnalysis.cpp updated: 1.134 -> 1.135
LiveIntervalAnalysis.h updated: 1.44 -> 1.45
---
Log message:

Allow the live interval analysis pass to be a bit more aggressive about
numbering values in live ranges for physical registers.

The alpha backend currently generates code that looks like this:

  vreg = preg
...
  preg = vreg
  use preg
...
  preg = vreg
  use preg

etc.  Because vreg contains the value of preg coming in, each of the 
copies back into preg contain that initial value as well.

In the case of the Alpha, this allows this testcase:

void "foo"(int %blah) {
        store int 5, int *%MyVar
        store int 12, int* %MyVar2
        ret void
}

to compile to:

foo:
        ldgp $29, 0($27)
        ldiq $0,5
        stl $0,MyVar
        ldiq $0,12
        stl $0,MyVar2
        ret $31,($26),1

instead of:

foo:
        ldgp $29, 0($27)
        bis $29,$29,$0
        ldiq $1,5
        bis $0,$0,$29
        stl $1,MyVar
        ldiq $1,12
        bis $0,$0,$29
        stl $1,MyVar2
        ret $31,($26),1

This does not seem to have any noticable effect on X86 code.

This fixes PR535: http://llvm.cs.uiuc.edu/PR535 .

 This will generate a bytecode file that can be executed.
 
-CHANGES:
-========
-This pre-release has the following changes:
-
-	- Pool Allocator Optimization pass is now separate from LLVM and
-	  compiled into a shared object.  The LLVM utilities do not need to be
-	  recompiled when the pool allocator code is changed.
-	- Correctly handles indirect calls.
-	- Correctly handles globals.
-	- Accepts partially pool allocatable programs.
-	- Fixed a large number of bugs.
-	- Tested on a number of benchmarks including Olden, Ptrdist, and a few
-	  SPEC codes.
-
 BUGS:
 =====
 Please see our website for information on how to report bugs

+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */
