Re: gcj, libgcj, and GNU JVM for AIX

["Hill, Dean L" <DHill4 at LNC dot com>]

(I'm emailing this issue to you because andrew29@littlepinkcloud.invalid responded to my gnu.gcc.help post on 12/26/03. I've also posted a copy of this email to gnu.gcc.help under the same title as the subject of this email. Any help you can give is appreciated.)

Okay, I've almost built libgcj from source by using gcc binaries I downloaded from Bull Freeware.

With the help of a co-worker (and a lot of tweaking), we've built the following components successfully:
zlib
fastjar
libibery
boehm-gc
libffi

However, making libjava fails due to an assembler error.  When prims.cc is compiled, with the following command:
c++ -mpowerpc -DHAVE_CONFIG_H -I. -I../../libjava -I./include -I./gcj -I../../libjava -Iinclude -I../../libjava/include -I../../libjava/../boehm-gc/include -I../../libjava/libltdl -I../../libjava/libltdl -I../../libjava/.././libjava/../gcc -I../../libjava/../zlib -I../../libjava/../libffi/include -I../libffi/include -fno-rtti -fnon-call-exceptions -fdollars-in-identifiers -Wswitch-enum -W -Wall -D_GNU_SOURCE -DPREFIX=\"/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.3\" -g -O2 -Wp,-MD,.deps/prims.pp -c ../../libjava/prims.cc   -DPIC -o .libs/prims.o

We get the output:

To diagnose the problem, I had the compiler generate the assembler source (prims.s).  Then I used the gcc assembler to assemble prims.s.  I got the same syntax errors.  Inspecting the offending lines, we noticed some dollar signs "$", e.g.:
        .tc _ZN4java4lang30ArrayIndexOutOfBoundsException6class$ETC],_ZN4java4lang30Array
IndexOutOfBoundsException6class$E[RW]

I manually removed the dollar signs from each line and the file assembled fine.  So, why does prims.cc generate prims.s with dollar signs in symbol names?

I tried changing the c++ option -fdollars-in-identifiers to -fno-dollars-in-identifiers with no change in the generated assembler code.

How do I have the c++ compiler NOT generate dollar signs in the assembler code?
