Brian Gaeke 49e14432c2 Make the write*map methods more self-contained. Document some more.

2003-06-03 19:30:15 +00:00
Brian Gaeke 71ab329f08 I documented this file, in an attempt to understand it, with a view toward
rewriting it.  I also vacuumed out all the commented-out code and
inaccurate comments, etc.

(We need to put the mapping information in a data structure so that we can
pass it out to the JIT, instead of automagically converting it to .byte
directives.)

2003-06-03 03:20:57 +00:00
Misha Brukman b54bf54065 Store instructions are different from other Format 3.1/3.2 instructions in that
they prefer the destination register to be last. Thus, two new classes were made
for them that accomodate for having this layout of operands (F3_1rd, F3_2rd).

2003-06-03 03:20:14 +00:00
Misha Brukman bbd10f96a2 * Added section A.34: Move FP register on int reg condition (FMOVr)
* Labeled sections that are not currently used in the Sparc backend as not
  requiring completion at this time.

Misha Brukman f545b2402f Added MOVR (move int reg on register condition), aka comparison with zero.
None of these instructions are actually used in the Sparc backend, so no changes
were required in the instruction selector.

Misha Brukman 843d6933a0 SparcInstr.def: added 'r' and 'i' versions of MOV(F)cc instructions
SparcInstrSelection.cpp:
* Fixed opcodes to return correct 'i' version since the two functions are each
  only used in one place.
* Changed name of function to have an 'i' in the name to signify that they each
  return an immediate form of the opcode.
* Added a warning if either of the functions is ever used in a context which
  requires a register-version opcode.

SparcV9_F4.td: fixed class F4_3, added F4_4 and notes that F4_{1,2} need fixing
SparcV9.td: added the MOV(F)cc instructions

llvm-svn: 6548

llvm-svn: 6503
2003-06-01 02:48:23 +00:00
Vikram S. Adve ba6f8e274a Several bug fixes: globals in call operands were not being pulled out;
globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

llvm-svn: 6466
2003-05-31 07:34:57 +00:00
Vikram S. Adve a83804a29a Extensive changes to the way code generation occurs for function
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

Misha Brukman 87cbd97710 The actual order of parameters in a 2-reg-immediate assembly instructions is
"rs1, imm, rd": most importantly, rd goes last.

Misha Brukman a853af587a Moved and expanded convertOpcodeFromRegToImm() to conver more opcodes.

Misha Brukman c1830a472a Make LLI behave just like LLC with regard to the compile passes it uses.
llvm-svn: 6444
2003-05-30 20:00:13 +00:00
Misha Brukman 39dfa6a920 Made the register and immediate versions of instructions consecutive.
llvm-svn: 6439
2003-05-30 19:14:01 +00:00
Misha Brukman f6e4dce74c Because the format of the shift instructions is `shift r, shcnt, r', the
instructions of format 3.12 and 3.13 cannot inherit from F3rdrs1, because that
implies that the two registers are the first two parameters to the instruction.

Thus I made the instructions inherit from F3rd again, and manually added an rs1
field AFTER the shcnt field in the instruction, which maps to the appropriate
place in the instruction.

The other changes are just elimination of unnecessary spaces.

2003-05-30 18:06:10 +00:00
Brian Gaeke d380f29377 Makefile: Make SparcV9CodeEmitter.inc depend on SparcV9_F*.td as well.
SparcV9_F3.td: F3_12 and F3_13 instructions have rd and rs1 fields. Also,
 their fields were totally screwed up. This seems to fix the problem.

llvm-svn: 6429
2003-05-30 08:02:14 +00:00
Misha Brukman 6ada87e6eb Since there is now another derived .inc file, ignore them all.
llvm-svn: 6411
2003-05-29 20:15:27 +00:00
Misha Brukman 9175a5de53 Use an absolute path to TableGen because not everyone (e.g. automatic tester)
has their path set up by this point.

llvm-svn: 6410
2003-05-29 20:09:56 +00:00
Misha Brukman 35d5512f34 When TableGen finds an error in the SparcV9.td file, it exits with a non-zero
exit code. This, in turn, makes an empty file SparcV9CodeEmitter.inc, and only
much later, produces a link error because the key function that TableGen creates
isn't found.

Using a temporary file in the middle forces a good .INC file to be generated by
TableGen, and it will keep trying until you fix the input file.

llvm-svn: 6392
2003-05-29 05:29:22 +00:00
Misha Brukman 794c8a1334 Fixed to use the correct format of the instruction.
llvm-svn: 6390
2003-05-29 04:53:56 +00:00
Misha Brukman 376dac2eed This should work better with re-generating the SparcV9CodeEmitter.inc file.
Also, added a rule to delete the generated .inc file on `make clean'.

Misha Brukman ea4f498395 * Broke up SparcV9.td into separate files as it was getting unmanageable

llvm-svn: 6388
2003-05-29 03:31:43 +00:00
Misha Brukman fded35952a Fixed ordering of elements in instructions: although the binary instructions
list (rd, rs1, imm), in that order (bit-wise), the actual assembly syntax is
instr rd, imm, rs1, and that is how they are constructed in the instruction
selector. This fixes the discrepancy.

Also fixed some comments along the same lines and fixed page numbers referring
to where instructions are described in the Sparc manual.

llvm-svn: 6377
2003-05-27 22:40:34 +00:00
Misha Brukman 96ce62a105 Added 'r' or 'i' annotations to instructions, as SparcInstr.def has changed.
Non-obvious change: since I have changed ST and STD to be STF and STDF to
(a) closer resemble their name (NOT assembly text) in the Sparc manual, and
(b) clearly specify that they they are floating-point opcodes,
I made the same changes in this file.

llvm-svn: 6376
2003-05-27 22:39:01 +00:00
Misha Brukman da83883ef1 Added 'r' or 'i' annotations to instructions, as SparcInstr.def has changed.
Here I had to make one non-trivial change: add a function to get a version of
the opcode that takes an immediate, given an opcode that takes all registers.

This is required because sometimes it is not known at construction time which
opcode is used because opcodes are passed around between functions.

llvm-svn: 6375
2003-05-27 22:37:00 +00:00
Misha Brukman 8bde6a688c Added 'r' or 'i' annotations to instructions, as SparcInstr.def has changed.
llvm-svn: 6373
2003-05-27 22:35:43 +00:00
Misha Brukman cb801a6884 Added entries for each of the instructions with annotations ('r' or 'i').
llvm-svn: 6372
2003-05-27 22:33:39 +00:00
Misha Brukman db69bebc89 One of the first major changes to make the work of JITting easier: adding
annotations on instructions to specify which format they are (i.e., do they take
2 registers and 1 immediate or just 3 registers) as that changes their binary
representation and hence, code emission.

This makes instructions more like how X86 defines them to be. Now, writers of
instruction selection must choose the correct opcode based on what instruction
type they are building, which they already know. Thus, the JIT doesn't have to
do the same work by `discovering' which operands an instruction really has.

As this involves lots of small changes to a lot of files in lib/target/Sparc,
I'll commit them individually because otherwise the diffs will be unreadable.

llvm-svn: 6371
2003-05-27 22:32:38 +00:00
Misha Brukman 8110439ff6 * Allow passing in an unsigned configuration to allocateSparcTargetMachine()

2003-05-27 22:01:10 +00:00
Misha Brukman e195b7c0fc Broke out class definition from SparcV9CodeEmitter, and added ability to take a

2003-05-27 21:45:05 +00:00
Misha Brukman 3e9272fb29 SparcV9CodeEmitter.cpp is a part of the Sparc code emitter. The main function
that assembles instructions is generated via TableGen (and hence must be built
before building this directory, but that's already the case in the top-level
Makefile).

Also added is .cvsignore to ignore the generated file `SparcV9CodeEmitter.inc',
which is included by SparcV9CodeEmitter.cpp .

Chris Lattner 74cb2d2503 Allow emission of names that start with an underscore. This is needed to
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

Vikram S. Adve 10d8164013 Several major fixes, particularly in emitting constant aggregates:
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

    to int reg. when calling a function with no prototype.
