I'm writing a compiler for a subset of java, and I'm almost done. The one thing I have problems with is handling classes, fields and method that are named like jasmin-keywords.
For example:
class Test {
public static void main(String[] args) {
int a;
a = new pop().run();
}
}
class pop {
int lcmp;
int stack;
int isub;
int iload_0;
public int run() {
int aaload;
lcmp = 1;
aaload = lcmp;
return aaload;
}
public int swap() {
return 0;
}
public int iload_0() {
int istore;
boolean ret;
return 0;
}
}
Which would compile into jasmin like this:
.source evul_names.java
.class Test
.super java/lang/Object
.method public <init>()V
aload_0
invokespecial java/lang/Object/<init>()V
return
.end method
.method public static main([Ljava/lang/String;)V
.limit locals 2
.limit stack 2
.var 0 is a I
.line 4
new pop
dup
invokespecial pop/<init>()V
invokevirtual pop/run()I
istore_0 ; a
return
.end method
.source evul_names.java
.class pop
.super java/lang/Object
.field public lcmp I
.field public stack I
.field public isub I
.field public iload_0 I
.method public <init>()V
aload_0
invokespecial java/lang/Object/<init>()V
return
.end method
.method public run()I
.limit locals 3
.limit stack 2
.line 15
.var 0 is <this> Lpop;
.var 1 is aaload I
.line 17
iconst_1
aload_0 ; this
swap
putfield pop/lcmp I
.line 18
aload_0 ; this
getfield pop/lcmp I
istore_1 ; aaload
.line 19
iload_1 ; aaload
ireturn
.end method
.method public swap()I
.limit locals 2
.limit stack 1
.line 22
.var 0 is <this> Lpop;
.line 23
iconst_0
ireturn
.end method
.method public iload_0()I
.limit locals 4
.limit stack 1
.line 26
.var 0 is <this> Lpop;
.var 1 is istore I
.var 2 is ret Z
.line 29
iconst_0
ireturn
.end method
The problem is the .class and .field directives, they cause compile error if the name is a keyword. I have tried putting both single quotes and double quotes around them; using single quotes the jasmin assembles into class files, but then one get verify error (and it seems like it actually includes the quotation in the name, which is suboptimal). Using double quotes it doesn't compile at all.
Is there any solution at all to this, or is it impossible to do this in jasmin?
