e27cbe6542 Hint label lookup table initialization branch on GOTO VM kind. 
This initialization is performed only once so it shall be marked as unexpected.

301ee26568 Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). 
CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE().
As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

48ed660cdf Make CALL VM with FP and IP in global registers not to return anything from opcode handlers. 
Set OPLINE to NULL to terminate VM loop instead.
This saves 1 CPU instruction for each opcode handler.

249c2323f4 Allow CALL executor to keep few very often used vaiables in CPU registers. 
This is disabled by default yet, but may be enabled compiling zend_execute.c with -DHAVE_GCC_GLOBAL_REGS.
Only tested on Linux x86 and x86_64 with GCC 4.9.2.

e112f6a04e second shot on removing TSRMLS_* 2014-12-14 14:07:59 +01:00

14e29f5146 Reduced size of zend_op on 64-bit systems. 
the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%.

The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets.

In run-time constant now should be accessed as:
  RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv
  EX_CONSTANT(opline->op1) instead of opline->op1.zv

Jump targets:
  OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr

The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.

f9927a6c97 Merge mainstream 'master' branch into refactoring 
During merge I had to revert:
	Nikita's patch for php_splice() (it probably needs to be applyed again)
	Bob Weinand's patches related to constant expression handling (we need to review them carefully)
	I also reverted all our attempts to support sapi/phpdbg (we didn't test it anyway)
