[Bug java/19295] New: Incorrect bytecode produced for bitwise AND


This is a boiled-down test case from part of Eclipse.  gcj produces this bytecode:

Method name:"isArrayType" public final Signature: ()boolean
Attribute "Code", length:35, max_stack:3, max_locals:1, code_length:11
  0: aload_0
  1: getfield <Field Test2.tagBits long>
  4: i2l

which results in a verification failure because it's producing an i2l
instruction when there's a long on the stack.

gcj4 --version
gcj4 (GCC) 4.0.0 20041228 (Red Hat 4.0.0-0.17) (i686-pc-linux)

$ gcj4 -C Test2.java; gcj4 -findirect-dispatch -c Test2.class
Test2.java: In class 'Test2':
Test2.java: In method 'Test2.isArrayType()':
Test2.java:5: error: verification failed: incompatible type on stack
Test2.java:5: error: expected type 'int' but stack contains 'void'
Test2.java:5: confused by earlier errors, bailing out
