* src/*.[ch]: Replaced `scm_mem2symbol' by `scm_from_locale_symboln' and `scm_ulong2num' by `scm_from_ulong'. * src/vm_system.c (tail-call): Fixed stack leak (SP lacked decrement by one more Scheme object in the tail-recursive case). * benchmark/measure.scm (measure): Make sure we are using the compiled procedure (i.e. a program object) when measuring. This yields better results than before. :-) * doc/guile-vm.texi: Augmented the instruction set documentation with branch instructions, `call' and `tail-call'. git-archimport-id: lcourtes@laas.fr--2004-libre/guile-vm--revival--0.6--patch-7 |
