Jakob Stoklund Olesen fb1249548f Tighten test case a bit. 
Ideally, we would match an S-register to its containing D-register, but that
requires arithmetic (divide by 2).

Chris Lattner 91328b317b Implement support for x86 fastisel of small fixed-sized memcpys, which are generated 
en-mass for C++ PODs.  On my c++ test file, this cuts the fast isel rejects by 10x 
and shrinks the generated .s file by 5%

Chris Lattner 5f4b783426 Implement support for fast isel of calls of i1 arguments, even though they are illegal, 
when they are a truncate from something else.  This eliminates fully half of all the 
fastisel rejections on a test c++ file I'm working with, which should make a substantial
improvement for -O0 compile of c++ code.

This fixed rdar://9297003 - fast isel bails out on all functions taking bools

Chris Lattner d7f7c93914 Handle i1/i8/i16 constant integer arguments to calls by prepromoting them. 
Before we would bail out on i1 arguments all together, now we just bail on
non-constant ones.  Also, we used to emit extraneous code.  e.g. test12 was:

	movb	$0, %al
	movzbl	%al, %edi
	callq	_test12

and test13 was:
	movb	$0, %al
	xorl	%edi, %edi
	movb	%al, 7(%rsp)
	callq	_test13f

Now we get:

	movl	$0, %edi
	callq	_test12
and:
	movl	$0, %edi
	callq	_test13f

 2011-04-19 04:36:17 +00:00
Chris Lattner c59290a34c be layout aware, to produce: 
testb	$1, %al
	je	LBB0_2
## BB#1:                                ## %if.then
	movb	$0, %al

instead of:

	testb	$1, %al
	jne	LBB0_1
	jmp	LBB0_2
LBB0_1:                                 ## %if.then
	movb	$0, %al

how 'bout that.

Chris Lattner 2c8a4c3b1b fix rdar://9297006 - fast isel bails out on trunc to i1 -> bools cry, 
a common cause of fast isel rejects on c++ code.

Greg Clayton 176761e530 Added a new option to the "source list" command that allows us to see where 
line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:

(lldb) source list -f test.c -l1 -c222 -b
       1   	#include <stdio.h>
       2   	#include <sys/fcntl.h>
       3   	#include <unistd.h>
       4   	int
       5   	sleep_loop (const int num_secs)
[2]    6   	{
       7   	    int i;
[1]    8   	    for (i=0; i<num_secs; ++i)
       9   	    {
[1]    10  	        printf("%d of %i - sleep(1);\n", i, num_secs);
[1]    11  	        sleep(1);       
       12  	    }
       13  	    return 0;
[1]    14  	}
       15  	
       16  	int 
       17  	main (int argc, char const* argv[])
[1]    18  	{
[1]    19  	    printf("Process: %i\n\n", getpid());
[1]    20  	    puts("Press any key to continue..."); getchar();
[1]    21  	    sleep_loop (20);
       22  	    return 12;
[1]    23  	}

Above we can see there are two breakpoints for line 6 and one breakpoint for
lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table
entries for them. This helps visualize the data provided in the debug 
information without having to manually dump all line tables. It also includes
all inline breakpoint that may result for a given file which can also be very
handy to see.

Evan Cheng 7d6cd4902e Change A9 scheduling itineraries VLD* / VST* entries default to "aligned". That 
is, it assumes addresses are 64-bit aligned (which should be the more common
case). If the alignment is found not to be aligned, then getOperandLatency()
would adjust the operand latency computation by one to compensate for it.

Greg Clayton 431ce67823 Fixed an issue where if you specify an architecture from the command line like: 
$ lldb --arch i386-unknown-unknown a.out

It would then create a target with only the "i386" part due to 
SBDebugger::GetDefaultArchitecture(...) truncating the arch triple due to the
way things used to be.
