* Remove unused private fields found by clang's new -Wunused-private-field.Benjamin Kramer2012-06-061-1/+0
| | | | | | | | There are some that I didn't remove this round because they looked like obvious stubs. There are dead variables in gtest too, they should be fixed upstream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158090 91177308-0d34-0410-b5e6-96231b3b80d8
* Reinstate -O3 for LTO.David Blaikie2012-05-301-3/+3
| | | | | | | | | | | | | | | | | This broke in r144788 when the CodeGenOpt option was moved from everywhere else (specifically, from addPassesToEmitFile) to createTargetMachine. Since LTOCodeGenerator wasn't passing the 4th argument, when the 4th parameter became the 3rd, it silently continued to compile (int->bool conversion) but meant something completely different. This change preserves the existing (accidental) and previous (default) semantics of the addPassesToEmitFile and restores the previous/intended CodeGenOpt argument by passing it appropriately to createTargetMachine. (discovered by pending changes to -Wconversion to catch constant->bool conversions) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157705 91177308-0d34-0410-b5e6-96231b3b80d8

* The internalize pass can be dangerous for LTO.Bill Wendling2012-04-051-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider the following program: $ cat main.c void foo(void) { } int main(int argc, char *argv[]) { foo(); return 0; } $ cat bundle.c extern void foo(void); void bar(void) { foo(); } $ clang -o main main.c $ clang -o bundle.so bundle.c -bundle -bundle_loader ./main $ nm -m bundle.so 0000000000000f40 (__TEXT,__text) external _bar (undefined) external _foo (from executable) (undefined) external dyld_stub_binder (from libSystem) $ clang -o main main.c -O4 $ clang -o bundle.so bundle.c -bundle -bundle_loader ./main Undefined symbols for architecture x86_64: "_foo", referenced from: _bar in bundle-elQN6d.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) The linker was told that the 'foo' in 'main' was 'internal' and had no uses, so it was dead stripped. Another situation is something like: define void @foo() { ret void } define void @bar() { call asm volatile "call _foo" ... ret void } The only use of 'foo' is inside of an inline ASM call. Since we don't look inside those for uses of functions, we don't specify this as a "use." Get around this by not invoking the 'internalize' pass by default. This is an admitted hack for LTO correctness. <rdar://problem/11185386> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154124 91177308-0d34-0410-b5e6-96231b3b80d8

* Make some headway towards compiling all of LLVM.Bill Wendling2012-03-292-36/+55
| | | | | | | | | | | | | | | | | | Module-level ASM may contain definitions of functions and globals. However, we were not telling the linker that these globals had definitions. As far as it was concerned, they were just declarations. Attempt to resolve this by inserting module-level ASM functions and globals into the '_symbol' set so that the linker will know that they have values. This gets us further towards our goal of compiling LLVM, but it still has problems when linking libLTO.dylib because of the `-dead_strip' flag that's passed to the linker. <rdar://problem/11124216> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153638 91177308-0d34-0410-b5e6-96231b3b80d8
