opcode

The easiest thing to boost performance of any PHP application (the "P" in LAMP, of course) is to take advantage of an opcode cache.

An opcode cache saves this compiled opcode and reuses it the next time the page is called.

If the program has more than one occurrence of the opcode, try to find the sequence printed by the handler code in the dump file.

In AT&T syntax, the size of memory operands is determined from the last character of the opcode name.

We see a much cleaner syntax for defining these functions, which can be optimized for performance by opcode caches.

Opcode caches have long been popular for PHP, with some of the first ones coming about back in the heyday of PHP V4.

Unlike APC and Wincache, it is only an opcode cache and optimizer, so it does not contain the user cache components.

The other idea everyone has when looking at this, sooner or later, is "Why not put the opcode-to-template translation table in the code? "

On top of the stack to the type specified in the opcode, and places that converted value on the top of the stack.

Opcode A sequence of bits that is recognized by the processor as one of the instructions in its instruction set.

Without a doubt, an opcode cache is the first step in speeding up PHP by removing the need to parse and compile a script on every request.

It's also possible that your distribution has already packaged an opcode cache, and you just have to install it.

Opcode is a single-byte instruction, and local represents a local variable with an index greater than Byte. MaxValue.

Using a single inline assembly opcode will probably work wonderfully on a uni-processor machine.

OP code caches are useful so that your script does not have to be compiled on every request.

File Cache - Even with the PHP opcode cache enabled, the PHP engine has to accesses the script files on a file system.

Alternative PHP Cache (APC) is probably the most popular opcode cache for PHP (see Resources).

Another speed enhancer is opcode optimization.

From this, we just had to find the opcode of this instruction to compute the key.

The best thing you can do for PHP is to install an opcode cache.

The RET instruction opcode always generates a near return.

ILGenerator. EmitCalli(Opcode, CallingConventions, Type, Type[], Type[]) for calls using a managed calling convention.

Alternative PHP Cache, is probably the most popular opcode cache for PHP.

The makers of Zend also have a commercial opcode cache that includes an optimizer to further increase efficiency.

To enable the opcode optimizer, add --enable-xcache-optimizer.

One major one is that it is compiled at runtime vs. compile time, which won't permit opcode caches to cache the function.

They contain details about the current opcode.

Ruby 1. 9, like Rubinius, compiles Ruby source code to opcodes which are then executed by it's opcode interpreter.

In the meantime, investigate one or more of the PHP accelerators and opcode optimizers.

ILGenerator. EmitCalli(Opcode, CallingConvention, Type, Type[]) for calls using an unmanaged calling convention.

It is generated under a variety of conditions, such as an illegal opcode, illegal operand, privileged opcode, and so on.

In this case, the failed opcode is 7c6000a6.

Opcode suffixes of b, w, and l specify byte (8-bit), word (16-bit), and long (32-bit) memory references.

For example, the processor might trap if an illegal opcode is found within the program.

If a serious error occurs, for example, an invalid opcode, the SPU is stopped and an interrupt is delivered to the PPE.

Opcode allows IL compilers to make a call to a virtual function in a uniform way independent of whether

This program will try to execute a privileged opcode

Invalid combination of opcode and operands

The following Emit method overload can use the ceq opcode
