The llvm-gcc 4.2 Ada compiler works fairly well, however this is not a mature
technology and problems should be expected.
<ul>
<li>
The Ada front-end currently only builds on x86-32. This is mainly due
to lack of trampoline support (pointers to nested functions) on other platforms,
however it
<a
href=
"http://llvm.org/PR2006"

also fails to build on x86-64
</a>
which does support trampolines.
</li>
<li>
The Ada front-end
<a
href=
"http://llvm.org/PR2007"
>
fails to bootstrap
</a>
.
Workaround: configure with --disable-bootstrap.

<li>

c393010
</a>
ACATS tests
fail (c380004 also fails with gcc-4.2 mainline).
</li>
<li>
Many gcc specific Ada tests continue to crash the compiler.
</li>
<li>
The -E binder option (exception backtraces)
<a
href=
"http://llvm.org/PR1982"
>
does not work
</a>
and will result in programs
crashing if an exception is raised. Workaround: do not use -E.
</li>
<li>
Only discrete types
<a
href=
"http://llvm.org/PR1981"
>
are allowed to start
or finish at a non-byte offset
</a>
in a record. Workaround: do not pack records
or use representation clauses that result in a field of a non-discrete type
starting or finishing in the middle of a byte.
</li>
<li>
The lli interpreter
<a
href=
"http://llvm.org/PR2009"

considers 'main'
as generated by the Ada binder to be invalid
</a>

Workaround: hand edit the file to use pointers for argv and envp rather than
integers.
