Michael J. Spencer 511dce004e CBackend: Fix MSVC build. 
This may produce warnings on MSVS, but it's better than failures.

Evan Cheng 367a5df8cf For each instruction itinerary class, specify the number of micro-ops each 
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.

This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

Bill Wendling cedf3a278d A script that tests a certain release candidate in several modes. It does a 
2-phase build of llvm and llvm-gcc, similar to what the buildbots do, and runs
the regression testsuite.

Things to do:

- Work out some bugs with llvm-gcc flags.
- Not all platforms support ObjC.
- Run the test-suite.

Chris Lattner abfe4223c2 generalize my previous operand loc info hack. If the same operand 
is busted for all variants, report it as the location.  This allows
us to get the operand right for bugs like:

t.s:3:12: error: invalid operand for instruction
	outb %al, %gs
	          ^

Even though there are reg/imm and reg/reg forms of this instruction.

llvm-svn: 113183
 2010-09-06 23:37:39 +00:00
Chris Lattner 339cc7bfef in the case where an instruction only has one implementation 
of a mneumonic, report operand errors with better location
info.  For example, we now report:

t.s:6:14: error: invalid operand for instruction
        cwtl $1
             ^

but we fail for common cases like:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^

because we don't know if this is supposed to be the reg/imm or imm/reg
form.

llvm-svn: 113178
 2010-09-06 22:11:18 +00:00
Chris Lattner 628fbecf4f Now that we know if we had a total fail on the instruction mnemonic, 
give a more detailed error.  Before:

t.s:11:4: error: unrecognized instruction
   addl $1, $1
   ^
t.s:12:4: error: unrecognized instruction
   f2efqefa $1
   ^

After:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^
t.s:12:4: error: invalid instruction mnemonic 'f2efqefa'
   f2efqefa $1
   ^

This fixes rdar://8017912 - llvm-mc says "unrecognized instruction" when it means "invalid operands"

Chris Lattner 8130197937 now that the opcode is trivially exposed, start matching instructions 
by doing a binary search over the mnemonic instead of doing a linear
search through all possible instructions.  This implements rdar://7785064

llvm-svn: 113171
 2010-09-06 21:22:45 +00:00
Chris Lattner 6b6f3dd994 emit the match table at global scope instead of within the 
MatchInstructionImpl. This makes it easier to read/understand
MatchInstructionImpl.

llvm-svn: 113170
 2010-09-06 21:08:38 +00:00
Chris Lattner 82d88ced92 special case the mnemonic operand of the instruction in the 
generated matcher, emiting it as a column in the MatchEntry
table instead of forcing it to go through classification and
everything else.  Making it be classified caused tblgen to
produce a ton of one-off classes for each mneumonic.  This
should reduce the size of the generated matcher significantly
while paving the way for future improvements.

llvm-svn: 113169
 2010-09-06 21:01:37 +00:00
Chris Lattner fdb7decfaf The "ambiguous instructions" check only produces anything with -debug, 
so only do the N^2 loop with debug mode.

llvm-svn: 113168
 2010-09-06 20:21:47 +00:00
Chris Lattner b4be28f33d have tblgen detect when an instruction would have matched, but 
failed because a subtarget feature was not enabled.  Use this to
remove a bunch of hacks from the X86AsmParser for rejecting things
like popfl in 64-bit mode.  Previously these hacks weren't needed,
but were important to get a message better than "invalid instruction"
when used in the wrong mode.

This also fixes bugs where pushal would not be rejected correctly in
32-bit mode (just pusha).

llvm-svn: 113166
 2010-09-06 20:08:02 +00:00

 2010-07-30 12:18:36 +00:00
Jim Grosbach d343166a0b Many Thumb2 instructions can reference the full ARM register set (i.e., 
have 4 bits per register in the operand encoding), but have undefined
behavior when the operand value is 13 or 15 (SP and PC, respectively).
The trivial coalescer in linear scan sometimes will merge a copy from
SP into a subsequent instruction which uses the copy, and if that
instruction cannot legally reference SP, we get bad code such as:
  mls r0,r9,r0,sp
instead of:
  mov r2, sp
  mls r0, r9, r0, r2

This patch adds a new register class for use by Thumb2 that excludes
the problematic registers (SP and PC) and is used instead of GPR
for those operands which cannot legally reference PC or SP. The
trivial coalescer explicitly requires that the register class
of the destination for the COPY instruction contain the source
register for the COPY to be considered for coalescing. This prevents
errant instructions like that above.

- The instructions are being added with dummy placeholder patterns using some 256

  generic enough to accept them,  when we go for codegen, the stuff will be already
  there.

- Use "Y" as suffix for those Instructions: MOVUPSYrr, ...
- All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX
  file.

Duncan Sands 408bb192de Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts" 
builds to "Release".  The default build is unchanged (optimization on,
assertions on), however it is now called Release+Asserts.  The intent
is that future LLVM releases released via llvm.org will be Release builds
in the new sense, i.e. will have assertions disabled (currently they have
assertions enabled, for a more than 20% slowdown).  This will bring them
in line with MacOS releases, which ship with assertions disabled.  It also
means that "Release" now means the same things in make and cmake builds:
cmake already disables assertions for "Release" builds AFAICS.

                            (mem_frag addr:$src2))))];

The right reference resolving should lead to:

                            (mem_frag addr:$src2))))];
But was yielding:

regclass to represent this.  Also fixes a couple of bugs.

Bob Wilson 6eae520de9 Add instruction encoding for the Neon VMOV immediate instruction. This changes 
the machine instruction representation of the immediate value to be encoded
into an integer with similar fields as the actual VMOV instruction.  This makes
things easier for the disassembler, since it can just stuff the bits into the
immediate operand, but harder for the asm printer since it has to decode the
value to be printed.  Testcase for the encoding will follow later when MC has
more support for ARM.

Jakob Stoklund Olesen 7de379467e Replace the SubRegSet tablegen class with a less error-prone mechanism. 
A Register with subregisters must also provide SubRegIndices for adressing the
subregisters. TableGen automatically inherits indices for sub-subregisters to
minimize typing.

CompositeIndices may be specified for the weirder cases such as the XMM sub_sd
index that returns the same register, and ARM NEON Q registers where both D
subregs have ssub_0 and ssub_1 sub-subregs.

It is now required that all subregisters are named by an index, and a future
patch will also require inherited subregisters to be named. This is necessary to
allow composite subregister indices to be reduced to a single index.
