Christopher Lamb 8448570beb PR400 work phase 1. Add attributed load/store instructions for volatile/align to LLVM.

Reid Spencer 4388f0b4fa For PR1146:
Make ParamAttrsList objects unique. You can no longer directly create or
destroy them but instead must go through the ParamAttrsList::get()
interface.

Reid Spencer 9c9741e864 Okay, yes there *is* a getKeyLength method on ValueName. And, it should be
used because we *do* want to allow nulls in names.

Reid Spencer 94bae69764 For PR1328:
Use the new parameter on Function::getIntrinsicID to identify cases where
a function is being called with an "llvm." name but it isn't actually an
intrinsic. In such cases generate an error.

Reid Spencer cf2ccbff1a For PR1289:
Check at the end of the parse that there are no unresolved types and no
undefined values. Issue errors if there are. This gets rid of the need
for implementation or checkpoint by ensuring you can't finish a parse with
undefined things.

Reid Spencer 01a599a202 Give users a grace period on the implementation keyword. This *will* get
removed in a few days.

llvm-svn: 35472
2007-03-29 18:49:28 +00:00
Reid Spencer 2e35a58838 Replace the "implementation" keyword with "checkpoint". This more accurately
describes its function as check against unresolved types and definitions.
This is handy for forcing error messages in assembly test cases or otherwise
ensuring that everything is resolved at that point in the assembly.

Reid Spencer fe65ae88fe For PR1248:
Eliminate support for type planes in numbered values. This simplifies the
data structures involved in managing forward definitions, etc. Instead of
requiring maps from type to value, we can now just use a vector of values.
These changes also required rewrites of some support functions such as
InsertValue, getBBVal, and ResolveDefinitions. Some other cosmetic changes
were made as well.

Reid Spencer 9875fc1500 Implement support for aribrary precision integers by creating two new
tokens: ESAPINTVAL and EUAPINTVAL and adding an APInt* as a semantic value.
This allows us to extend the definition of an integer constant to allow
arbitrary precision integer constant values.

Reid Spencer 3aaaa0b2bd For PR411:
This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

Reid Spencer de1d05f0f1 There is nothing exclamatory about an error message. No other compiler
or assembler uses ! at the end of every message. We shouldn't either.

Reid Spencer 2341c22ec7 Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

Anton Korobeynikov 037c867b54 Propagate changes from my local tree. This patch includes:
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.

Reid Spencer 082a77f1c9 For PR1117:

of any cast instruction.

Chris Lattner 03c4953cdd rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

Reid Spencer 7a9c62baa6 For PR1064:
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

Reid Spencer 32af9e8cc5 For PR411:
Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.

Reid Spencer 6c435f0fa0 For PR1077:
Disallow merging of dupliate global variables. It is now illegal to declare
or define two global variables of the same name and same type. llvm-gcc3 is
dead in 2.0 and llvm-gcc4 doesn't have that problem nor need the hack.

llvm-svn: 32933
2007-01-05 21:50:38 +00:00
Reid Spencer 136a91c4e7 Change the syntax for parameter attributes:
1. The @ sign is no longer necessary.
2. We now support "function attributes" as parameter attribute 0.
3. Instead of locating the return type attributes after the type of a
   function result, they are now located after the function header's
   closing paranthesis and before any alignment or section options.
4. The way has been prepared for a new "noreturn" function attribute but
   there is no support for recognizing it in the lexer nor doing anything
   with it if it does get set.
5. The FunctionType::getParamAttrsText method now has support for
   returning multiple attributes. This required a change in its interface.

I'm unhappy that this change leads to 6 new shift/reduce conflicts, but
in each case bison's decision to choose the shift is correct so there
shouldn't be any damage from these conflicts.
