* Formatting fixups.Eric Christopher2013-03-191-14/+14

* Extend TableGen instruction selection matcher to improve handlingUlrich Weigand2013-03-191-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of complex instruction operands (e.g. address modes). Currently, if a Pat pattern creates an instruction that has a complex operand (i.e. one that consists of multiple sub-operands at the MI level), this operand must match a ComplexPattern DAG pattern with the correct number of output operands. This commit extends TableGen to alternatively allow match a complex operands against multiple separate operands at the DAG level. This allows using Pat patterns to match pre-increment nodes like pre_store (which must have separate operands at the DAG level) onto an instruction pattern that uses a multi-operand memory operand, like the following example on PowerPC (will be committed as a follow-on patch): def STWU : DForm_1<37, (outs ptr_rc:$ea_res), (ins GPRC:$rS, memri:$dst), "stwu $rS, $dst", LdStStoreUpd, []>, RegConstraint<"$dst.reg = $ea_res">, NoEncode<"$ea_res">; def : Pat<(pre_store GPRC:$rS, ptr_rc:$ptrreg, iaddroff:$ptroff), (STWU GPRC:$rS, iaddroff:$ptroff, ptr_rc:$ptrreg)>; Here, the pair of "ptroff" and "ptrreg" operands is matched onto the complex operand "dst" of class "memri" in the "STWU" instruction.

* Unify clang/llvm attributes for asan/tsan/msan (LLVM part)Kostya Serebryany2013-02-261-9/+9
| | | | | | | | | | | | | | | | | | | | These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176075 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement the NoBuiltin attribute.Bill Wendling2013-02-221-0/+5
| | | | | | | | | The 'nobuiltin' attribute is applied to call sites to indicate that LLVM should not treat the callee function as a built-in function.

* Initial submission for the attribute group feature.Bill Wendling2013-02-061-0/+30
| | | | | | | | | | | | | | | | | | Attribute groups are of the form: #0 = attributes { noinline "no-sse" "cpu"="cortex-a8" alignstack=4 } Target-dependent attributes are represented as strings. Attributes can have optional values associated with them. E.g., the "cpu" attribute has the value "cortex-a8". Target-independent attributes are listed as enums inside the attribute classes. Multiple attribute groups can be referenced by the same object. In that case, the attributes are merged together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174493 91177308-0d34-0410-b5e6-96231b3b80d8

For backward compatibility, the values of CFLAGS and CXXFLAGS defaults to empty, overriding the default values provided by autoconf (for example, '-g -O2' when CC=gcc'). $(CPP) is not used by our makefiles. Therefore, the value of CPP is not passed to Makefile.config, despite beeing mentioned by 'configure --help'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174313 91177308-0d34-0410-b5e6-96231b3b80d8
