58b2315657 Beginnings of CPS section in manual 
* doc/ref/compiler.texi (Continuation-Passing Style): Beginnings of this
  section.  Will be finished when we fix implicit truncation.

660f2775e9 Fix cross-references in api-macros.texi 
* doc/ref/api-macros.texi (Macro Expansion): Fix cross-references.

fa48a2f79a (call-with-values foo (lambda (a . b) a)) avoids consing rest list 
* module/language/cps/slot-allocation.scm (allocate-slots): Don't
  allocate slots to unused results of function calls.  This can allow us
  to avoid consing a rest list for call-with-values with an ignored rest
  parameter, and can improve the parallel move code.

* module/language/cps/compile-bytecode.scm (compile-fun): Adapt to avoid
  emitting bind-rest in values context if the rest arg is unused.

70057f3408 vm: Gracefully handle stack overflows. 
Fixes <http://lists.gnu.org/archive/html/guile-user/2013-12/msg00017.html>.
Reported by rvclayton@verizon.net (R. Clayton).

* libguile/vm.c (reinstate_stack_reserve): New function.
  (vm_error_stack_overflow): Install it as an unwind handler.
* test-suite/tests/control.test ("the-vm")["stack overflow reinstates
  stack reserve"]: New test.

  of a revision.  CPS and bytecode are not done yet.

8567d28d60 x86: Correct wrong x87 optimization. 
* lib/jit_x86-x87.c: Correct wrong optimization when
	loading the log(2) constant.

0b0d63d892 x86: Ensure the x87 stack is empty when calling a function. 
* lib/jit_x86-cpu.c: Use the emms instruction before
	calling any function. This is particularly important
	when using c99 complex functions as it can easily
	overflow the x87 stack due to the way lightning uses
	the x87 stack as a flat register file.
 2013-12-03 15:09:48 -02:00
pcpa
c162b9d836 x86: Correct wrong x87 float indexed store code generation. 
* lib/jit_x86-x87.c: Correct wrong code generation due
	to comparing the base and not the value register with
	%st(0) in stxi_f.
