Included mjsunit JavaScript test suite and C++ unit tests. In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

#include "src/disassembler.h"
[arm][turbofan] Pass double immediate to vmov as uint64_t On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN.

[arm] Clean up use of IsSupported and IsEnabled. CpuFeatures::IsSupported(feature) indicates that the feature is available on the target. AssemblerBase::IsEnabled(feature) indicates that we've checked for support (using CpuFeatureScope). The main benefit is that we can test on (for example) ARMv8, but have some assurance that we won't generate ARMv8 instructions on ARMv7 targets. This patch simply cleans up the usage, which had become inconsistent. The instruction emission functions now check not only that their dependent features are supported, but also that we've verified that using CpuFeatureScope.

[arm] Pass float immediates to vmov as uint32_t This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN. New in this CL: Although src/double.h existed already, src/float.h did not exist yet.

Cleaned up CpuFeature scope handling. First of all, it has nothing to do with Isolates, it is related to the assembler at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up some platform-specific stuff on the way.

[arm][turbofan] Pass double immediate to vmov as uint64_t On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN.

Added a version of the v8::HandleScope constructor with an Isolate and use that consistently. I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.

More OStreamsUse OStreams more often. This is a mostly mechanical CL (more than 90% Emacs macros and query-replace-regexp) moving FILE*/StringStream*-based APIs to OStream-based APIs.

Fixed a bug in the chaining of fixup position The ARM and MIPS assemblers had a bug where they did not handle the last element in the list of code positions correctly during the fixup of offsets for forward jumps. This happened when the first instruction contained a forward jump to a label, and that label was used in a forward jump later, too. Unified the code for Assembler::next on ARM and MIPS while we were there. Added test cases, even for ia32/x64, which seem to be correct, even I don't fully understand why... %-} BUG=v8:1644 Review URL: http://codereview.chromium.org/7786001 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@9063 ce2b1a6d-e550-0410-aec6-3dcde31c8c00

[arm] Clean up use of IsSupported and IsEnabled. CpuFeatures::IsSupported(feature) indicates that the feature is available on the target. AssemblerBase::IsEnabled(feature) indicates that we've checked for support (using CpuFeatureScope). The main benefit is that we can test on (for example) ARMv8, but have some assurance that we won't generate ARMv8 instructions on ARMv7 targets. This patch simply cleans up the usage, which had become inconsistent. The instruction emission functions now check not only that their dependent features are supported, but also that we've verified that using CpuFeatureScope.

[arm][turbofan] Pass double immediate to vmov as uint64_t On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN.

[arm] Pass float immediates to vmov as uint32_t This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN. New in this CL: Although src/double.h existed already, src/float.h did not exist yet. I created the file in this CL, and moved the classes Float32 and Float64 there, which already existed in src/deoptimizer.h.

// vdup (from scalar).
[arm] Pass float immediates to vmov as uint32_t This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN. New in this CL: Although src/double.h existed already, src/float.h did not exist yet. I created the file in this CL, and moved the classes Float32 and Float64 there, which already existed in src/deoptimizer.h.

[arm] Pass float immediates to vmov as uint32_t This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN. New in this CL: Although src/double.h existed already, src/float.h did not exist yet.

// vceq (float).
[arm] Pass float immediates to vmov as uint32_t This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN.

[compiler] Delay allocation of code-embedded heap numbers. Instead of allocating and embedding certain heap numbers into the code during code assembly, emit dummies but record the allocation requests. Later then, in Assembler::GetCode, allocate the heap numbers and patch the code by replacing the dummies with the actual objects. The RelocInfos for the embedded objects are already recorded correctly when emitting the dummies.

Fix a crash when generating forward jumps to labels at very high assembly offsets The first jump to a specific label was marked as jump to absolute position -4. This value was stored in the assembly as a branch to a offset (-4 - (instruction offset + 8)). The offset is only 24 bit long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow the offset. Fix by denoting the first jump to a label by storing the jump instruction location as the target. This will result in offset of -8, which of course always fits in the branch instruction.

[compiler] Delay allocation of code-embedded heap numbers. Instead of allocating and embedding certain heap numbers into the code during code assembly, emit dummies but record the allocation requests. Later then, in Assembler::GetCode, allocate the heap numbers and patch the code by replacing the dummies with the actual objects. The RelocInfos for the embedded objects are already recorded correctly when emitting the dummies.

[arm] Pass float immediates to vmov as uint32_t This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN. New in this CL: Although src/double.h existed already, src/float.h did not exist yet. I created the file in this CL, and moved the classes Float32 and Float64 there, which already existed in src/deoptimizer.h.

[compiler] Delay allocation of code-embedded heap numbers. Instead of allocating and embedding certain heap numbers into the code during code assembly, emit dummies but record the allocation requests. Later then, in Assembler::GetCode, allocate the heap numbers and patch the code by replacing the dummies with the actual objects. The RelocInfos for the embedded objects are already recorded correctly when emitting the dummies.

[arm] Introduce UseScratchRegisterScope Introduce a stripped down version of UseScratchRegisterScope for ARM and use it inside the assembler and macro-assembler. At the exception of the Call instructions, we now use this scope instead of using the ip register directly. This is inspired from how the ARM64 backend works. In general, the benefit of doing this is we can catch cases where ip is being used both by the caller and by the assembler. But more specifically, TurboFan reserves r9 as an extra scratch register because ip can already be used by the assembler. With this utility, we can isolate the cases in the code generator which need an extra register and potentially fix them, allowing us to give r9 back to the register allocator. This patch uncovered places in the assembler where we were using ip unconditionally when we could have re-used the destination register instead.

Assembler assm(isolate, nullptr, 0);
[arm] Support splitting add with immediate instructions When an immediate does not fit an add instruction we use a temporary register to hold the value, using movw/movt to encode it. However, in order to remove a use of r9 in TurboFan's code generator, we need to cope with no scratch registers being available. That is to say that the destination and source registers are the same, and `ip` is not available to use. In this case, we can split an add instruction into a sequence of additions: ``` UseScratchRegisterScope temps(...); Register my_scratch = temps.Acquire(); __ add(r0, r0, Operand(0xabcd); // add r0, r0, #0xcd // add r0, r0, #0xab00 ``` As a drive-by fix, make the disassembler test fail if we expected a different number of instructions generated.

Included mjsunit JavaScript test suite and C++ unit tests. In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
