llvm-svn: 24300
2005-11-11 16:47:30 +00:00
Andrew Lenharth bd0127e467 Add support for a cycle counter intrinsic. As basically all processors have
this and have it in about the same form, I think this makes sense.
on X86, you do a RDTSC (64bit result, from any ring since the P5MMX)
on Alpha, you do a RDCC
on PPC, there is a sequence which may or may not work depending on how things
are setup by the OS.  Or something like that.  Maybe someone who knows PPC
can add support.  Something about the time base register.
on Sparc, you read %tick, which in some solaris versions (>=8) is readable by
userspace
on IA64 read ar.itc

So I think the ulong is justified since all of those are 64bit.
Support is slighly flaky on old chips (P5 and lower) and sometimes
depends on OS (PPC, Sparc).  But for modern OS/Hardware (aka this decade),
we should be ok.

I am still not sure what to do about lowering.  I can either see a lower to 0, to
gettimeofday (or the target os equivalent), or loudly complaining and refusing to
continue.

I am commiting an Alpha implementation.  I will add the X86 implementation if I
have to (I have use of it in the near future), but if someone who knows that
backend (and the funky multi-register results) better wants to add it, it would
take them a lot less time ;)

Chris Lattner e1d34bac0b Allow per-character control over what target assemblers allow in symbol
names.  This also changes the default to allow all of "$_." in addition

markCharUnacceptable to remove one of these or markCharAcceptable to add
to the set.  This corresponds with what GAS accepts by default.

Do not mangle internal global names that do not collide with anything.

        .asciz  "foo"

Chris Lattner aba48dd34c Clean up RemoveDeadNodes significantly, by eliminating the need for a temporary
set and eliminating the need to iterate whenever something is removed (which
can be really slow in some cases).  Thx to Jim for pointing out something silly
I was getting stuck on. :)

Chris Lattner 88e234dd49 Add a new option to indicate we want the code generator to emit code quickly,
not spending tons of time microoptimizing it.  This is useful for an -O0

Nate Begeman 3ee3e69556 Add the necessary support to the ISel to allow targets to codegen the new
alignment information appropriately.  Includes code for PowerPC to support
fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.

Chris Lattner dd0c174082 Turn sdiv into udiv if both operands have a clear sign bit. This occurs
a few times in crafty:

OLD:    %tmp.36 = div int %tmp.35, 8            ; <int> [#uses=1]
NEW:    %tmp.36 = div uint %tmp.35, 8           ; <uint> [#uses=0]
OLD:    %tmp.19 = div int %tmp.18, 8            ; <int> [#uses=1]
NEW:    %tmp.19 = div uint %tmp.18, 8           ; <uint> [#uses=0]
OLD:    %tmp.117 = div int %tmp.116, 8          ; <int> [#uses=1]
NEW:    %tmp.117 = div uint %tmp.116, 8         ; <uint> [#uses=0]
OLD:    %tmp.92 = div int %tmp.91, 8            ; <int> [#uses=1]
NEW:    %tmp.92 = div uint %tmp.91, 8           ; <uint> [#uses=0]

Which all turn into shrs.

Chris Lattner e9ff0eaf5b Turn srem -> urem when neither input has their sign bit set. This triggers
8 times in vortex, allowing the srems to be turned into shrs:

OLD:    %tmp.104 = rem int %tmp.5.i37, 16               ; <int> [#uses=1]
NEW:    %tmp.104 = rem uint %tmp.5.i37, 16              ; <uint> [#uses=0]
OLD:    %tmp.98 = rem int %tmp.5.i24, 16                ; <int> [#uses=1]
NEW:    %tmp.98 = rem uint %tmp.5.i24, 16               ; <uint> [#uses=0]
OLD:    %tmp.91 = rem int %tmp.5.i19, 8         ; <int> [#uses=1]
NEW:    %tmp.91 = rem uint %tmp.5.i19, 8                ; <uint> [#uses=0]
OLD:    %tmp.88 = rem int %tmp.5.i14, 8         ; <int> [#uses=1]
NEW:    %tmp.88 = rem uint %tmp.5.i14, 8                ; <uint> [#uses=0]

NEW:    %tmp.85 = rem uint %tmp.5.i9, 1024              ; <uint> [#uses=0]
OLD:    %tmp.82 = rem int %tmp.5.i, 512         ; <int> [#uses=2]
NEW:    %tmp.82 = rem uint %tmp.5.i1, 512               ; <uint> [#uses=0]
OLD:    %tmp.48.i = rem int %tmp.5.i.i161, 4            ; <int> [#uses=1]
NEW:    %tmp.48.i = rem uint %tmp.5.i.i161, 4           ; <uint> [#uses=0]
OLD:    %tmp.20.i2 = rem int %tmp.5.i.i, 4              ; <int> [#uses=1]
NEW:    %tmp.20.i2 = rem uint %tmp.5.i.i, 4             ; <uint> [#uses=0]

it also occurs 9 times in gcc, but with odd constant divisors (1009 and 61)
so the payoff isn't as great.
