nickysn fbd05c4e12 * Improved code generation in tcg8086.g_flags2reg for the case when target reg 
size is >=16-bit:
  o Generated code is now one instruction and one byte shorter.
  o No 8-bit subregisters are used, which reduces register pressure.

cpubase.inc Implement support for saving and restoring address registers. 2013-10-05 21:43:42 +00:00

n8086mat.pas + enabled the use of the DIV/IDIV instruction for 16-bit div/mod on i8086 2013-11-11 22:34:41 +00:00
n8086mem.pas + getting the address of a label now returns a far pointer in i8086 far code memory models; this fixes the call to fpc_raiseexception in the raise node 2013-09-17 22:45:13 +00:00
r8086ari.inc * x86 targets: Profiling shows that quite a bit of time is spent in findreg_by_number(), despite it uses binary search. Worse, it is repeated for every piece of register information. Trying to get rid of some of these calls: rearranged registers so that their "opcode" matches 3 LSBs of superregister number (with a few exceptions described at the beginning of x86reg.dat). This allows to lookup opcodes in regval() with O(1) complexity, and removes need in rXXXop.inc files. 2013-10-03 08:08:04 +00:00
