Re-work bit/bits value resolving in tblgen

2012-09-06T23:32:48Z

- This patch is inspired by the failure of the following code snippet which is used to convert enumerable values into encoding bits to improve the readability of td files. class S { bits<2> V = !if(!eq(s, 8), {0, 0}, !if(!eq(s, 16), {0, 1}, !if(!eq(s, 32), {1, 0}, !if(!eq(s, 64), {1, 1}, {?, ?})))); } Later, PR8330 is found to report not exactly the same bug relevant issue to bit/bits values. - Instead of resolving bit/bits values separately through resolveBitReference(), this patch adds getBit() for all Inits and resolves bit value by resolving plus getting the specified bit. This unifies the resolving of bit with other values and removes redundant logic for resolving bit only. In addition, BitsInit::resolveReferences() is optimized to take advantage of this origanization by resolving VarBitInit's variable reference first and then getting bits from it. - The type interference in '!if' operator is revised to support possible combinations of int and bits/bit in MHS and RHS. - As there may be illegal assignments from integer value to bit, says assign 2 to a bit, but we only check this during instantiation in some cases, e.g. bit V = !if(!eq(x, 17), 0, 2); Verbose diagnostic message is generated when invalid value is resolveed to help locating the error. - PR8330 is fixed as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163360 91177308-0d34-0410-b5e6-96231b3b80d8

Convert all tests using TCL-style quoting to use shell-style quoting.

2012-07-02T12:47:22Z

This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for range expressions in TableGen foreach loops.

2012-05-24T22:17:39Z

Like this: foreach i = 0-127 in ... Use braces for composite ranges: foreach i = {0-3,9-7} in ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157432 91177308-0d34-0410-b5e6-96231b3b80d8

Don't put TGParser scratch results in the output.

Add Foreach Loop

2012-02-22T16:09:41Z

Add some data structures to represent for loops. These will be referenced during object processing to do any needed iteration and instantiation. Add foreach keyword support to the lexer. Add a mode to indicate that we're parsing a foreach loop. This allows the value parser to early-out when processing the foreach value list. Add a routine to parse foreach iteration declarations. This is separate from ParseDeclaration because the type of the named value (the iterator) doesn't match the type of the initializer value (the value list). It also needs to add two values to the foreach record: the iterator and the value list. Add parsing support for foreach. Add the code to process foreach loops and create defs based on iterator values. Allow foreach loops to be matched at the top level. When parsing an IDValue check if it is a foreach loop iterator for one of the active loops. If so, return a VarInit for it. Add Emacs keyword support for foreach. Add VIM keyword support for foreach. Add tests to check foreach operation. Add TableGen documentation for foreach. Support foreach with multiple objects. Support non-braced foreach body with one object. Do not require types for the foreach declaration. Assume the iterator type from the iteration list element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151164 91177308-0d34-0410-b5e6-96231b3b80d8

Replace all instances of dg.exp file with lit.local.cfg, since all tests are run with LIT now and now Dejagnu. dg.exp is no longer needed.

Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8

Add an (interleave A, B, ...) SetTheory operator.
