Chris Lattner fb70cf528e Fairly major change: emit fixed sized allocas in the entry block as a variable,
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.

Misha Brukman 0ccdecbdaa ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT :::
The JIT is designed to code-generate a function at-a-time. That means that any
pass can only make local changes to its function. Period.

Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding
globals to the Module, it cannot be run with the other passes, because by this
time, the globals have been output already by the JIT, and the addresses of any
globals appearing AFTER this point are not recognized.

However, the PreSelection pass is a requirement for correctness in the Sparc
codegen path, so it MUST be run.

This avoid generating a register to hold C, which in turn speeds up the

  also speeds up other passes.  This also speeds up execution of the program

Misha Brukman efafdf8046 * Instead of re-inventing the MachineConstantPool emitter that's already given
in Emitter.cpp, just convert the Sparc version of the constant pool into
  what's already supported and inter-operate.
* Implemented a first pass at lazy function resolution in the JITResolver. That
  required adding a SparcV9CodeEmitter pointer to simplify generating
  bit-patterns of the instructions.
* SparcV9CodeEmitter now creates and destroys static TheJITResolver, which makes
  sense because the SparcV9CodeEmitter is the only user of TheJITResolver, and
  lives for the entire duration of the JIT (via PassManager which lives in VM).
* Changed all return values in the JITResolver to uint64_t because of the 64-bit
  Sparc architecture.
* Added a new version of getting the value of a GlobalValue in the
  SparcV9CodeEmitter, which now works for already-generated functions (JITted or
  library functions).
* Removed little-used and unused functions, cleaning up the internal view of the
  SparcV9CodeEmitter.

Misha Brukman 1d443d1250 * Institute a hack for the Sparc call to mmap() to get our generated code to be
laid out closer to the VM so that calls to library functions (e.g. puts()) and
  callback (e.g.  JITResolver::CompilationCallback) fit into 30 bits of the call
  instruction.
* Abort if architecture is not yet supported (not X86 or Sparc) because it
  likely requires a different set of parameters to mmap() .
* Stop using hard-coded values for page size; use sysconf(_SC_PAGESIZE) instead.

Misha Brukman 4e7bad01ff I have finally seen the light. The code to change the opcode must live higher in
the loop, and in both cases. In the first case, it is a VReg that is a constant
so it may be actually converted to a constant. In the second case, it is already
a constant, but then if it doesn't change its type (e.g. to become a register
and have the value loaded from memory if it is too large to live in its
instruction field), we must change the opcode BEFORE the 'continue', otherwise
we miss the opportunity.

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

llvm-svn: 6470
2003-05-31 07:41:54 +00:00
Vikram S. Adve ad83684c77 Added MachineCodeForInstruction object as an argument to
TmpInstruction constructors because every TmpInstruction object has
to be registered with a MachineCodeForInstruction to prevent leaks.
This simplifies the user's code.

Vikram S. Adve c468882155 Allow explicit physical registers for implicit operands.
llvm-svn: 6468
2003-05-31 07:39:06 +00:00
Vikram S. Adve 465f9b6738 Changes to allow explicit physical register arguments that have been
preallocated.  While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

llvm-svn: 6467
2003-05-31 07:37:05 +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.

llvm-svn: 6438
2003-05-30 18:09:57 +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.

llvm-svn: 6437

llvm-svn: 6396

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 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

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.

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: 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.

Misha Brukman 80f0eb3a82 Link in Sparc libs for the JIT, even on X86 to be able to support debugging
of Sparc JIT (printing out instrs) on X86. Con: this increases linking time.

llvm-svn: 6361
2003-05-27 21:42:05 +00:00
Misha Brukman 56d27325c0 Allow for specification of which JIT to run on the commandline.
`lli -march=x86' or `lli -march=sparc' will forcefully select the JIT even on a
different platform. Running lli without the -march option will select the JIT
for the platform that it's currently running on.

Pro: can test Sparc JIT (debug printing mode) on X86 -- faster to compile/link
LLVM source base to test changes.
Con: Linking lli on x86 now pulls in all the Sparc libs -> longer link time
(but X86 can bear it, right?)

In the future, perhaps this should be a ./configure option to enable/disable
target JITting...

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 .

Misha Brukman a45606276d Fixed compilation errors, command-line argument declarations, cleaned up code to
look nicer and removed useless stuff.

Also renamed a few variables, moved them into namespaces, converted outputting
to a file into a print to std::cerr with a DEBUG() guard, as all passes should
do anyway.

No functional changes have been made. However, this code now compiles.

Misha Brukman 218a732724 Made the code readable:
* Lines must be wrapped at 80 chars. This is a hard limit.
* Consistent style on functions, braces, if, for, etc. Code must be readable.

No functional changes have been made, even though I added a new typedef.

Chris Lattner 9023155621 Initial checkin of PRE on LLVM. This implementation is still lacking in
several ways:

 * Load expressions are not PRE'd well.  Alias Analysis should be used to
   get accurate information when computing anticipatibility.
 * The expression collection implementation does not handle PHI nodes properly,
   thus the implementation misses many opportunities to PRE.
 * This code could be sped up quite a bit

Despite these flaws, the code seems to work well, and handles PR's as one
would expect.
