* Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman2009-06-042-6/+12
| | | | | | | | | | | | | | | | integer and floating-point opcodes, introducing FAdd, FSub, and FMul. For now, the AsmParser, BitcodeReader, and IRBuilder all preserve backwards compatability, and the Core LLVM APIs preserve backwards compatibility for IR producers. Most front-ends won't need to change immediately. This implements the first step of the plan outlined here: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8

* Second installment of "BasicBlock operands to the back"Gabor Greif2009-03-131-2/+2
| | | | | | | | | | | | | | | | | | | changes. For InvokeInst now all arguments begin at op_begin(). The Callee, Cont and Fail are now faster to get by access relative to op_end(). This patch introduces some temporary uglyness in CallSite. Next I'll bring CallInst up to a similar scheme and then the uglyness will magically vanish. This patch also exposes all the reliance of the libraries on InvokeInst's operand ordering. I am thinking of taking care of that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66920 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-072-8/+16
| | | | | | | | | | | | | | | | | | | | | | and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8

* Introducing nocapture, a parameter attribute for pointers to indicate that theNick Lewycky2008-12-152-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | callee will not introduce any new aliases of that pointer. The attributes had all bits allocated already, so I decided to collapse alignment. Alignment was previously stored as a 16-bit integer from bits 16 to 32 of the attribute, but it was required to be a power of 2. Now it's stored in log2 encoded form in five bits from 16 to 21. That gives us 11 more bits of space. You may have already noticed that you only need four bits to encode a 16-bit power of two, so why five bits? Because the AsmParser accepted 32-bit alignments, even though we couldn't store them (they were silently discarded). Now we can store them in memory, but not in the bitcode. The bitcode format was already storing these as 64-bit VBR integers. So, the bitcode format stays the same, keeping the alignment values stored as 16 bit raw values. There's some hideous code in the reader and writer that deals with this, waiting to be ripped out the moment we run out of bits again and have to replace the parameter attributes table encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61019 91177308-0d34-0410-b5e6-96231b3b80d8

Also, rename the recently added bitcode opcode FUNC_CODE_INST_VCMP to FUNC_CODE_INST_CMP2 and make the bitcode writer use it to handle fcmp/icmp on scalars or vectors. In the bitcode writer, use FUNC_CODE_INST_CMP for vfcmp/vicmp only. In the bitcode reader, have FUNC_CODE_INST_CMP handle icmp/fcmp returning bool, for backwards compatibility with existing bitcode files.
