* Doubleword Shift Left Logical Plus 32Jack Carter2012-07-161-0/+45
| | | | | | | | | | | | | | | | | | | | | | Mips shift instructions DSLL, DSRL and DSRA are transformed into DSLL32, DSRL32 and DSRA32 respectively if the shift amount is between 32 and 63 Here is a description of DSLL: Purpose: Doubleword Shift Left Logical Plus 32 To execute a left-shift of a doubleword by a fixed amount--32 to 63 bits Description: GPR[rd] <- GPR[rt] << (sa+32) The 64-bit doubleword contents of GPR rt are shifted left, inserting zeros into the emptied bits; the result is placed in GPR rd. The bit-shift amount in the range 0 to 31 is specified by sa. This patch implements the direct object output of these instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160277 91177308-0d34-0410-b5e6-96231b3b80d8
* The Mips specific relocation R_MIPS_GOT_DISP Jack Carter2012-07-131-0/+18
| | | | | | | | | | | 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

* This allows hello world to be compiled for Mips 64 direct object.Jack Carter2012-06-271-0/+39
| | | | | | | | | | | | It takes advantage of r159299 which introduces relocation support for N64. elf-dump needed to be upgraded to support N64 relocations as well. This passes make check. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159302 91177308-0d34-0410-b5e6-96231b3b80d8
* PR13013: ELF Type identification fails for MSB type ELF files.Meador Inge2012-06-251-0/+11
| | | | | | | | | | Fix 'sys::IdentifyFileType' to work with big and little endian byte orderings when reading the ELF object file type. Initial patch by Stefan Hepp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159138 91177308-0d34-0410-b5e6-96231b3b80d8
* Make the following changes in MipsAsmPrinter.cpp:Akira Hatanaka2012-05-121-1/+3
| | | | | | | | | | | - Remove code which lowers pseudo SETGP01. - Fix LowerSETGP01. The first two of the three instructions that are emitted to initialize the global pointer register now use register $2. - Stop emitting .cpload directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156689 91177308-0d34-0410-b5e6-96231b3b80d8
* Insert instructions to the entry basic block which initializes the globalAkira Hatanaka2012-05-121-1/+3
| | | | | | | | | | | | | | | | | | | | pointer register. This is the first of the series of patches which clean up the way global pointer register is used. The patches will make the following improvements: - Make $gp an allocatable temporary register rather than reserving it. - Use a virtual register as the global pointer register and let the register allocator decide which register to assign to it or whether spill/reloads are needed. - Make sure $gp is valid at the entry of a called function, which is necessary for functions using lazy binding. - Remove the need for emitting .cprestore and .cpload directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156671 91177308-0d34-0410-b5e6-96231b3b80d8
* This patch fixes 3 problems:Akira Hatanaka2012-04-161-10/+10
| | | | | | | | | | | | | | | 1. CHECKNEXT was used instead of CHECK-NEXT which caused the line to be ignored which in turn hid the next 2 problems: 2. ('sh_offset', 0x{{{[0-9,a-f]+}}) had one too many leading curly braces and failed to do it's job of accepting all hex digits and: 3. The check for the hex values for the code instructions didn't account for blank separators. Patch by Jack Carter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154842 91177308-0d34-0410-b5e6-96231b3b80d8

* Initial 64 bit direct object support.Akira Hatanaka2012-04-021-5/+30
| | | | | | | | | | | | This patch allows llvm to recognize that a 64 bit object file is being produced and that the subsequently generated ELF header has the correct information. The test case checks for both big and little endian flavors. Patch by Jack Carter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153889 91177308-0d34-0410-b5e6-96231b3b80d8
* Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnuEli Bendersky2012-03-251-8/+1
| | | | | | | | | | | | | | | | | | * Removed test/lib/llvm.exp - it is no longer needed * Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files left in the test suite so this code is no longer required. test/lit.cfg is now much shorter and clearer * Removed a lot of duplicate code in lit.local.cfg files that need access to the root configuration, by adding a "root" attribute to the TestingConfig object. This attribute is dynamically computed to provide the same information as was previously provided by the custom getRoot functions. * Documented the config.root attribute in docs/CommandGuide/lit.pod git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153408 91177308-0d34-0410-b5e6-96231b3b80d8
