Hi all:
A small question on ldc and ldc_w instruction: it seems that asm does
not distinguish these two instructions, right? I mean if i want to insert
new LdcInsnNode(xxx).
For example, I found the code like:
new LdcInsnNode("String content");
will sometimes produces ldc "string content", while some times produces
Ldc_w "string content".
and seems does related to the length of string?
Does any one have idea on this point? Will this "unpredictability" produce
some unexpected
side-effect? or how asm decide to Ldc or Ldc_w?
thanks
