2013-04-19[mips] First patch which adds support for micromips.Akira Hatanaka
This patch adds support for recoded (meaning assembly-language compatible to standard mips32) arithmetic 32-bit instructions. Patch by Zoran Jovanovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179873 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-17Mips assembler: Enable handling of nested expressionsJack Carter
This patch allows the Mips assembler to parse and emit nested expressions as instruction operands. It also extends the expansion of memory instructions when an offset is given as an expression. Contributer: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179657 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-22Fix the invalid opcode for Mips branch instructions in the assemblerJack Carter
For mips a branch an 18-bit signed offset (the 16-bit offset field shifted left 2 bits) is added to the address of the instruction following the branch (not the branch itself), in the branch delay slot, to form a PC-relative effective target address. Previously, the code generator did not perform the shift of the immediate branch offset which resulted in wrong instruction opcode. This patch fixes the issue. Contributor: Vladimir Medic git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177687 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-15Remove a final dependency on the form field in tablegen; which is a remnantReed Kotler
of the old jit and which we don't intend to support in mips16 or micromips. This dependency is for the testing of whether an instruction is a pseudo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175297 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-21Mips direct object xgot supportJack Carter
This patch provides support for the MIPS relocations: *) R_MIPS_GOT_HI16 *) R_MIPS_GOT_LO16 *) R_MIPS_CALL_HI16 *) R_MIPS_CALL_LO16 These are used for large GOT instruction sequences. Contributer: Jack Carter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168471 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-03This patch moves from using a hard coded number (4) Jack Carter
for the number of bytes in a particular instruction to using const MCInstrDesc &Desc = MCII.get(TmpInst.getOpcode()); Desc.getSize() This is necessary with the advent of 16 bit instructions with mips16 and micromips. It is also puts Mips in compliance with the other targets for getting instruction size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165171 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-02The mips 64bit instructions DSLL, DSRA, DSRL, DEXT and DINS get transformed ↵Jack Carter
by the assembler or through codegen direct object output to other variants based on the value of the immediate values of the operands. If the code is generated as assembler, this transformation does not occur assuming that it will occur later in the assembler. This code was originally called from MipsAsmPrinter.cpp and we needed to check for OutStreamer.hasRawTextSupport(). This was not a good place for it and has been moved to MCTargetDesc/MipsMCCodeEmitter.cpp where both direct object and the assembler use it it automagically. The test cases have been checked in for a number of weeks now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165067 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-06Mips relocations R_MIPS_HIGHER and R_MIPS_HIGHEST.Jack Carter
These 2 relocations gain access to the highest and the second highest 16 bits of a 64 bit object. R_MIPS_HIGHER %higher(A+S) The %higher(x) function is [ (((long long) x + 0x80008000LL) >> 32) & 0xffff ]. R_MIPS_HIGHEST %highest(A+S) The %highest(x) function is [ (((long long) x + 0x800080008000LL) >> 48) & 0xffff ]. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161348 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-13The Mips specific relocation R_MIPS_GOT_DISP Jack Carter
is used in cases where global symbols are directly represented in the GOT and we use an offset into the global offset table. This patch adds direct object support for R_MIPS_GOT_DISP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160183 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-11Mips MC object code emission improvements:Bruno Cardoso Lopes
"With this patch we can now generate runnable Mips code through LLVM direct object emission. We have run numerous simple programs, both C and C++ and with -O0 and -O3 from the output. The code is not production ready, but quite useful for experimentation."
