2009-08-02Remove unneeded intrinsics from Blackfin backend.Jakob Stoklund Olesen
__builtin_bfin_ones does the same as ctpop, so it can be implemented in the front-end. __builtin_bfin_loadbytes loads from an unaligned pointer with the disalignexcpt instruction. It does the same as loading from a pointer with the low bits masked. It is better if the front-end creates a masked load. We can always instruction select the masked to disalignexcpt+load. We keep csync/ssync/idle. These intrinsics represent instructions that need workarounds for some silicon revisions. We may even want to convert inline assembler to intrinsics to enable the workarounds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77917 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-02Scavenger asserts.Jakob Stoklund Olesen
Allow imp-def and imp-use of anything in the scavenger asserts, just like the machine code verifier. Allow redefinition of a sub-register of a live register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77904 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-02Add support for CPU features (i.e., bugs) and workarounds.Jakob Stoklund Olesen
This is just the framework to identify the needed workarounds. They are not actually implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77902 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Inline assembly support for Blackfin.Jakob Stoklund Olesen
We use the same constraints as GCC, including those that are slightly insane for inline assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77899 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Analog Devices Blackfin back-end.Jakob Stoklund Olesen
Generate code for the Blackfin family of DSPs from Analog Devices: http://www.analog.com/en/embedded-processing-dsp/blackfin/processors/index.html We aim to be compatible with the exsisting GNU toolchain found at: http://blackfin.uclinux.org/gf/project/toolchain The back-end is experimental. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Avoid forming a SELECT_CC in a type that the target doesn'tDan Gohman
support. This isn't immediately interesting, because Legalize ends up lowering SELECT_CC if the target doesn't support it, but this simplifies the process. Also, if the SELECT_CC would be expanded in Legalize, it can potentially end up with two copies of the condition expression. By leaving it as SELECT+SETCC, the SELECT can be expanded into two SELECTs that use a single SETCC. The two comparisons are usually CSE'd, but depending on when various expressions get legalized, the comparison expression could involve calls to library functions, such that the comparison expression may not be able to be CSE'd. This will be needed by a future patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77896 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-02ARM TAI no longer needs a TM, but createTargetAsmInfo() still does.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77878 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Move the getInlineAsmLength virtual method from TAI to TII, whereChris Lattner
the only real caller (GetFunctionSizeInBytes) uses it. The custom ARM implementation of this is basically reimplementing an assembler poorly for negligible gain. It should be removed IMNSHO, but I'll leave that to ARMish folks to decide. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77877 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-02Fix some fixme's in #if 0'd code by making it dependent on the structuralChris Lattner
behavior of the LSDA section instead of on some random target hook that needs to be kept in synch with other points of truth. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77855 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02move getDwarfExceptionSection from TAI to TLOF and rename it to Chris Lattner
getLSDASection() to be more specific. This makes it pretty obvious that the ELF LSDA section is being specified wrong in PIC mode. We're probably getting a lot of startup-time relocations to a readonly page, which is expensive and bad. Someone who cares about ELF C++ should investigate this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77847 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-01(re)introduce new simpler apis for creation sectionkinds.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77834 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01Remove "JumpTableDataSection" from TAI, instead, have AsmPrinterChris Lattner
compute it based on what it knows. As part of this, rename getSectionForMergeableConstant to getSectionForConstant because it works for non-mergable constants also. The only functionality change from this is that Xcore will start dropping its jump tables into readonly section instead of data section in -static mode. This should be fine as the linker resolves the relocations. If this is a problem, let me know and we'll come up with another solution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77833 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01give alpha its readonly section. This optimizes alpha, and prevents aChris Lattner
