* Mark 36 tests as XFAIL:vg_leak in llvm/test/TableGen.NAKAMURA Takumi2013-11-10
| | | | | | | In historical reason, tblgen is not strictly required to be free from memory leaks. For now, I mark them as XFAIL, they could be fixed, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194353 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm/test/TableGen: Remove XFAIL:vg_leak in dozen of tests, according to ↵NAKAMURA Takumi2012-12-11

* Re-work bit/bits value resolving in tblgenMichael Liao2012-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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<int 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

* Add support for using the `!if' operator when initializing variables:Bill Wendling2010-12-13
| | | | | | | | | | | | class A<bit a, bits<3> x, bits<3> y> { bits<3> z; let z = !if(a, x, y); } The variable z will get the value of x when 'a' is 1 and 'y' when a is '0'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121666 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for XFAILing valgrind runs with memory leak checking independentlyJeffrey Yasskin2010-03-20
| | | | | | | | | | of runs without leak checking. We add -vg to the triple for non-checked runs, or -vg_leak for checked runs. Also use this to XFAIL the TableGen tests, since tablegen leaks like a sieve. This includes some valgrindArgs refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99103 91177308-0d34-0410-b5e6-96231b3b80d8
