* Factor out the code for determining when symblic addressesDan Gohman2008-09-264-17/+50
| | | | | | | | | | require RIP-relative addressing and use it to fix a bug in X86FastISel in x86-64 PIC mode, where it was trying to use base/index registers with RIP-relative addresses. This fixes a bunch of x86-64 testsuite failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56676 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56628 91177308-0d34-0410-b5e6-96231b3b80d8
