* - Initialize "--no-builtin" to "false".Bill Wendling2008-09-301-1/+1
| | | | | | - Testcase for r56885. llvm-svn: 56886
* Add the new `-no-builtin' flag. This flag is meant to mimic the GCCBill Wendling2008-09-305-29/+37
| | | | | | | | | `-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero" instead of "__bzero" on Darwin10+. This arguably violates the meaning of this flag, but is currently sufficient. The meaning of this flag should become more specific over time. llvm-svn: 56885

* Optimize SelectionDAG's AssignTopologicalOrder even further.Dan Gohman2008-09-303-32/+67
| | | | | | | | | | | | | | | | | | | Completely eliminate the TopOrder std::vector. Instead, sort the AllNodes list in place. This also eliminates the need to call AllNodes.size(), a linear-time operation, before performing the sort. Also, eliminate the Sources temporary std::vector, since it essentially duplicates the sorted result as it is being built. This also changes the direction of the topological sort from bottom-up to top-down. The AllNodes list starts out in roughly top-down order, so this reduces the amount of reordering needed. Top-down is also more convenient for Legalize, and ISel needed only minor adjustments. llvm-svn: 56867

* Revert commit 56835 since it breaks the build.Duncan Sands2008-09-303-20/+8
| | | | | | | | | | "If a re-materializable instruction has a register operand, the spiller will change the register operand's spill weight to HUGE_VAL to avoid it being spilled. However, if the operand is already in the queue ready to be spilled, avoid re-materializing it". llvm-svn: 56837

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | information is in an unreachable block, then it's possible that the high/low pc values won't be set for the dwarf information. E.g., this function: void abort(void) __attribute__((__noreturn__)); void dead_beef(void) __attribute__ ((noreturn)); int *b; void dead_beef(void) { *b=0xdeadbeef; abort(); } has a call to "@llvm.dbg.region.end" only in the unreachable block: define void @dead_beef() noreturn nounwind { entry: call void @llvm.dbg.func.start(...) call void @llvm.dbg.stoppoint(...) ... call void @abort( ) noreturn nounwind unreachable return: ; No predecessors! call void @llvm.dbg.stoppoint(...) call void @llvm.dbg.region.end(...) ret void } The dwarf information emitted is something like: 0x00000084: TAG_subprogram [5] AT_name( "dead_beef" ) AT_external( 0x01 ) AT_prototyped( 0x01 ) AT_decl_file( 0x01 ) AT_decl_line( 0x08 ) Note that this is *not* the best fix for this problem, but a band-aid for an gaping wound. This code needs to be changed when we revamp our debugging information. llvm-svn: 56628
