Jul 16, 2010 · GCJ does produce native machine code, and not just an executable environment with embedded interpreter and bytecode. libgcj provides a bytecode interpreter to support calls from native code into Java bytecode, not to interpret the compiled program. If libgcj did not provide a bytecode interpreter, GCJ would not comply to the Java spec. –
GCJ will compile both source (.java) and bytecode (.class) files. However, in many cases the native code produced by compiling from source is better optimized than that compiled from .class files. Per Bothner explains: The reason is that when you compile to bytecode you lose a lot of information about program structure etc.

Oct 23, 2015 · 3. A Java compiler produces code for the JVM. So the target machine of a compiler can be a virtual machine that is not executed directly by the hardware. The main difference between interpreter and compiler is that a compiler first checks and translates the whole source code into a target machine language.
It has option to compile java to NATIVE code, not only to byte code. Generally speaking, around 80 % percent of Java code (base librarires) can be compiled directly to machine code. Java compiler that comes with JDK can of course do no such thing. It compiles to intermediate language ByteCode, which is in turn interpreted in Java Virtual ...
Sep 11, 2006 · GCJ is a portable, optimizing, ahead-of-time compiler for the Java Programming Language. It can compile Java source code to Java bytecode (class files) or directly to native machine code, and Java bytecode to native machine code. Compiled applications are linked with the GCJ runtime, libgcj, which provides the core class libraries, a garbage ...

The GNU Compiler for Java (GCJ) is a discontinued free compiler for the Java programming language. It was part of the GNU Compiler Collection. [3][4] GCJ compiles Java source code to Java virtual machine (JVM) bytecode or to machine code for a number of CPU architectures. It could also compile class files and whole JARs that contain bytecode ...
