| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ConstantFP::get(Type*, double) is unreliably host-specific: it can't handle a type like PPC128 on an x86 host. It even has a comment to that effect: "This should only be used for simple constant values like 2.0/1.0 etc, that are known-valid both as host double and as the target format." Instead, use APFloat. While we're at it, randomize the floating point value more thoroughly; it was previously limited to the range 0 to 2**19 - 1.

| * Teach LLVM about a PIE option which, when enabled on top of PIC, makesChandler Carruth2012-04-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | optimizations which are valid for position independent code being linked into a single executable, but not for such code being linked into a shared library. I discussed the design of this with Eric Christopher, and the decision was to support an optional bit rather than a completely separate relocation model. Fundamentally, this is still PIC relocation, its just that certain optimizations are only valid under a PIC relocation model when the resulting code won't be in a shared library. The simplest path to here is to expose a single bit option in the TargetOptions. If folks have different/better designs, I'm all ears. =] I've included the first optimization based upon this: changing TLS models to the *Exec models when PIE is enabled. This is the LLVM component of PR12380 and is all of the hard work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154294 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. The main works will made in the RuntimeDyLdImpl with uses the ObjectFile class. RuntimeDyLdMachO and RuntimeDyLdELF now only parses relocations and resolve it. This is allows to make improvements of the RuntimeDyLd more easily. In addition the support for COFF can be easily added. 2. Added ARM relocations to RuntimeDyLdELF. 3. Added support for stub functions for the ARM, allowing to do a long branch. 4. Added support for external functions that are not loaded from the object files, but can be loaded from external libraries. Now MCJIT can correctly execute the code containing the printf, putc, and etc. 5. The sections emitted instead functions, thanks Jim Grosbach. MemoryManager.startFunctionBody() and MemoryManager.endFunctionBody() have been removed. 6. MCJITMemoryManager.allocateDataSection() and MCJITMemoryManager. allocateCodeSection() used JMM->allocateSpace() instead of JMM->allocateCodeSection() and JMM->allocateDataSection(), because I got an error: "Cannot allocate an allocated block!" with object file contains more than one code or data sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153754 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

The first commit seems to be the real culprit, but I couldn't revert a smaller number of patches.
