[Sablevm-developer] Incrasing SVM_FRAME_NATIVE_REFS_MIN

[Grzegorz B. P. <ga...@de...>]

Hi Etienne,

In Debian packages I want to incrase the number of native references
to something nearer to what Sun's JVM makes available (max about 100
AFAIR, can't find it now). Putting aside fact that apps that don't work
with 16 refs are in 99% of cases broken, I'd like to make sure it won't
hurt too much.

$ grep -R SVM_FRAME_NATIVE_REFS_MIN . 
./constants.h:#define SVM_FRAME_NATIVE_REFS_MIN 16
./native.c:      method->data.native_method->refargs_count +
SVM_FRAME_NATIVE_REFS_MIN;
./native.c:      method->data.native_method->refargs_count +
SVM_FRAME_NATIVE_REFS_MIN;
./prepare.c:	    (((SVM_FRAME_NATIVE_REFS_MIN + 2) +
./thread.c:  jint lrefs_count = SVM_FRAME_NATIVE_REFS_MIN;

So I don't see anything that would effectively bind maximum
value "by design" (like using some bit operations where each
bit is for one reference or similar). So besides incrasing
memory usage, possibly decrasing execution speed, what can
be the other consequences of doing that? Anything I should
really be afraid of?

Hoping for quick and short answer,

PS: I want to upload something in shape of the final packages
that would make it into testing, before we release 1.1.1 with
GNU Classpath 0.08, which I think should happen soon after
0.08 release, next monday.
