* Adds the ability to run the llvm test suite in-tree.Chris Wailes2014-06-061-3/+9
| | | | | | | | | | | | | | | | | This was accomplished by building additional tools and hand-generating several files that are auto-generated by the configuration system when LLVM is built out-of-tree. The LTO, Interpreter, and DebugInfo libraries are now being compiled, and several source files were added to existing compilation targets. To run these tests you must first run build/envsetup.sh and have used lunch to select a target. You can then launch the test script by running: cd $ANDROID_BUILD_TOP/external/llvm && ./android_test.sh Bug: 15433215 Change-Id: I43d87de0a4620cdd46c8d0f825dd4428e8409702

When switching modes in an assembly file (e.g. arm to thumb mode) we would always emit the opcode from the original mode. Consider this small example: $ cat align.s .code 16 foo: add r0, r0 .align 3 add r0, r0 $ llvm-mc -triple armv7-none-linux align.s -filetype=obj -o t.o $ llvm-objdump -triple thumbv7 -d t.o Disassembly of section .text: foo: 0: 00 44 add r0, r0 2: 00 f0 20 e3 blx #4195904 6: 00 00 movs r0, r0 8: 00 44 add r0, r0 This shows that we have actually emitted an arm nop (e320f000) instead of a thumb nop. Unfortunately, this encodes to a thumb branch which causes bad things to happen when compiling assembly code with align directives. The fix is to notify the ARMAsmBackend when we switch mode. The MCMachOStreamer was already doing this correctly. This patch makes the same change for the MCElfStreamer. There is still a bug in the way nops are emitted for alignment because the MCAlignment fragment does not store the correct mode. The ARMAsmBackend will emit nops for the last mode it knew about. In the example above, we still generate an arm nop if we add a `.code 32` to the end of the file.

With this patch we use simple names for COMDAT sections (like .text or .bss). This matches the MSVC behavior. When merging it is the COMDAT symbol that is used to decide if two sections should be merged, so there is no point in building a fancy name.

This is the first step to fix pr17918. It extends the .section directive a bit, inspired by what the ELF one looks like. The problem with using linkonce is that given .section foo .linkonce.... .section foo .linkonce we would already have switched sections when getting to .linkonce. The cleanest solution seems to be to add the comdat information in the .section itself. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195822 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks.

| | | | | | | | | | | | | | | | | | | | | | Accepting quotes is a property of an assembler, not of an object file. For example, ELF can support any names for sections and symbols, but the gnu assembler only accepts quotes in some contexts and llvm-mc in a few more. LLVM should not produce different symbols based on a guess about which assembler will be reading the code it is printing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194575 91177308-0d34-0410-b5e6-96231b3b80d8

| * MC asm parser: allow ?'s in symbol names, and handle @'s in names in MS asmHans Wennborg2013-10-183-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is another (final?) stab at making us able to parse our own asm output on Windows. Symbols on Windows often contain @'s and ?'s in their names. Our asm parser didn't like this. ?'s were not allowed, and @'s were intepreted as trying to reference PLT/GOT/etc. We can't just add quotes around the bad names, since e.g. for MinGW, we use gas to assemble, and it doesn't like quotes in some places (notably in .def directives). This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS assembly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason this got reverted was that the @feat.00 symbol which was emitted for every TU became quoted, and on cygwin/mingw we use the gas assembler which couldn't handle the quotes. This commit fixes the problem by only emitting @feat.00 for win32, where we use clang -cc1as to assemble. gas would just drop this symbol anyway, so there is no loss there. With @feat.00 gone, there shouldn't be quoted symbols showing up on cygwin since it uses the Itanium ABI, which doesn't put these funny characters in symbols. > Because of win32 mangling, we produce symbol and section names with > funny characters in them, most notably @ characters. > > MC would choke on trying to parse its own assembly output.

| * Add a MCTargetStreamer interface.Rafael Espindola2013-10-088-195/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192181 91177308-0d34-0410-b5e6-96231b3b80d8

| * Remove some really nasty uses of hasRawTextSupport.Rafael Espindola2013-10-057-45/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192035 91177308-0d34-0410-b5e6-96231b3b80d8

| * [MC][AsmParser] Hook for post assembly file processingJack Carter2013-10-041-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch handles LLVM standalone assembler (llvm-mc) ELF flag setting based on input file directive processing. Mips assembly requires processing inline directives that directly and indirectly affect the output ELF header flags. This patch handles one ".abicalls". To process these directives we are following the model the code generator uses by storing state in a container as we go through processing and when we detect the end of input file processing, AsmParser is notified and we update the ELF header flags through a MipsELFStreamer method with a call from MCTargetAsmParser::emitEndOfAsmFile(MCStreamer &OutStreamer). This patch will allow other targets the same functionality. Jack git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191982 91177308-0d34-0410-b5e6-96231b3b80d8

E.g., on a vector shuffle operation with a memory operand, disassembled outputs are: * Without the option: vpshufd $-0x79, (%rsp), %xmm0 * With the option: vpshufd $-0x79, (%rsp), %xmm0 ## Latency: 5 The printed latency is extracted from the schedule model available in the disassembler context. Thus, this option has no effect if there is not a scheduling model for the target. This boils down to one may need to specify the CPU string, so that this option could have an effect. Note: Latency < 2 are not printed. This part of <rdar://problem/14687488>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191859 91177308-0d34-0410-b5e6-96231b3b80d8
