8g: compute register liveness during regopt · 84f291b1

0018 (x.go:5) MOVL    AX,autotmp_0001+-28(SP)

0025 (x.go:5) CALL    ,runtime.printnl+0(SB)
0026 (x.go:6) RET     ,

is problematic because the liveness range for
autotmp_0000 (0006-0009) is nested completely
inside a span where BX holds a live value (0003-0015).
Because the register allocator only looks at 0006-0009
to see which registers are used, it misses the fact that
BX is unavailable and uses it anyway.

The n->pun = anyregalloc() check in tempname is
a workaround for this bug, but I hit it again because
I did the tempname call before allocating BX, even
though I then used the temporary after storing in BX.
This should fix the real bug, and then we can remove
the workaround in tempname.

The code creates pseudo-variables for each register
and includes that information in the liveness propagation.
Then the regu fields can be populated using that more
complete information.  With that approach, BX is marked
as in use on every line in the whole span 0003-0015,
so that the decision about autotmp_0000
(using only 0006-0009) still has all the information
it needs.

This is not specific to the 386, but it only happens in
generated code of the form

        load R1
        ...
        load var into R2
        ...
        store R2 back into var
        ...
        use R1

and for the most part the other compilers generate
the loads for a given compiled line before any of
the stores.  Even so, this may not be the case everywhere,
so the change is worth making in all three.

8l, ld: Initial adjustments for Plan 9 native compilation of 8l · 9baaa6f7

Lucio De Re authored Jun 03, 2011

These changes are not particularly invasive and have been tested
as broadly as possible.

8l/l.h:
  -	#pragma varargck: added some, removed duplicates.

ld/dwarf.c:
  -	As Plan 9 has no NULL, changed all occurrences to nil.
  -	Added USED(size); where necessary.
  -	Added (void) argument in definition of finddebugruntimepath().
  -	Plan 9 compiler was complaining about multiple
        assignments, repeaired by breaking up the commands.
  -	Correction: havedynamic = 1; restored.

ld/go.c:
  -	Needed USED(file); in two functions.
  -	Removed unused assignments flagged by the Plan 9 compiler.

ld/lib.c:
  -	Replaced unlink() with remove() which seems available everywhere.
  -	Removed USED(c4); and USED(magic) no longer required.
  -	Removed code flagged as unused by the Plan 9 compiler.
  -	Added attributes to a number of format strings.

This is in preparation of escape analysis; function parameters

sync/atomic: fix check64 · 69cb8fef

Russ Cox authored Jun 02, 2011

The LDREXD and STREXD instructions require
aligned addresses, and the ARM stack is not
guaranteed to be aligned during the check.
This may cause other problems later (on the ARM
not all 64-bit pointers may be 64-bit aligned)
but at least the check is correct now.
