[fpc-pascal] Some questions regarding jvmbackend port

[leledumbo]

I finally managed to compile the latest revision of jvmbackend port, however
I've got some problems during compilation and execution:

1. The wiki instruction

The first paragraph says:

"Building the JVM compiler, RTL and utilities is currently not yet supported
using the top-level makefile"

yet in "Building the compiler and RTL" section it says:

"Execute the following command in the top level directory of the checked out
sources"

which in turn would execute the top-level makefile, right? The fact is that
I can only compile through this top-level makefile, compiling directly from
each directory (i.e. compiler, rtl, utils) doesn't work, the makefile
doesn't understand jvm-java/jvm-android target.

In "Building the fpcjres utility":

Again "Run the following command in the top level directory of the checked
out sources", however running "make all" doesn't build anything from utils
directory, it builds ppc386 and rtl though. For this one, I must cd to
utils/fpcres manually and execute the command from there (the previous "make
all" is required, because it's used to compile fpc(j)res).

Using simple script, I can now install everything to the normal fpc
binary/library tree.

2. Execution

I try a simple hello world program:

uses
  jdk15;
begin
  jlsystem.fout.println('hello, world');
end.

Executing ppcjvm -vt hello.pas gives:

... // unimportant lines

The assembler used is supposed to be jasmin.jar, right? So what is this
jvm-java-java for? If it's for executing jasmin, it should be plain java and
I already have it installed and tested.
