124074 - Mozilla 0.9.8 will not compile with ccc/cxx (Compaq C/C++ compilers)

Status: VERIFIED DUPLICATE of bug 48516

(SeaMonkey :: Build Config, defect, P4)

Description

[vsync]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.7) Gecko/20011223
BuildID:    20020206

There are non-portable __asm__ constructs in
mozilla/xpcom/reflect/xptcall/src/md/unix/xptcinvoke_linux_alpha.cpp.  

Additionally, horrible linking errors are spewed from libxpcom.so when trying to
link mozilla/xpcom/tools/registry/regExport.

Reproducible: Didn't try
Steps to Reproduce:
1. Download Mozilla.
2. ./configure CC=ccc CCC=cxx
3. Cry.

Actual Results:  cxx: Info: Switch -pthread not supported on this
platform...ignoring.
cxx: Error: xptcinvoke_linux_alpha.cpp, line 47: expected a "{"
asm("invoke_copy_to_stack") __attribute__((unused));
^
cxx: Warning: xptcinvoke_linux_alpha.cpp, line 51: parsing restarts here after
          previous syntax error
{

cxx: Error: xptcinvoke_linux_alpha.cpp, line 101: this declaration has no

    "#### XPTC_InvokeByIndex ####\n"
----^
cxx: Info: 3 errors detected in the compilation of "xptcinvoke_linux_alpha.cpp".



If I do "make CC=gcc CCC=cxx" in that directory and continue the build, I later
on get:

Expected Results:  A compiled Mozilla.

When built with gcc, Mozilla is _pathetically_ slow on my 533MHz EV56 AlphaPC
164LX.  Considering that it _flies_ on my 500MHz Celeron-based laptop, I'm a bit
annoyed.  I have heard that the Compaq compilers produce ~30% faster output, so
I wanted to try them, but it appears the Mozilla source is full of proprietary
gcc-only constructs.

I note that the UNIX build instructions do not say that gcc is required...

Jim^2, could either of you shed some light on this?  I see that the dec1
tinderbox is using cc/cxx to compile.  Has xptcall only been ported for gcc on
linux alpha?

vsync, can you attach a log of the configure run as well as config.log &
config/autoconf.mk?

Comment 2

[Jim Dunn]

64bit... I can't even deal with 2bits...
I am adding shanmu who has been working on 
OSF/Tru64 builds maybe he can help.  Either
technically or asking around to others at
compaq who might be able to help.

Comment 3

[jim_nance]

You cant build mozilla with gcc on the alpha.  The xptcall stuff only works
with cxx.

jim_nance:

Perhaps you are referring to Tru64?  All I know is that I'm on Linux/Alpha, and
0.9.8 built properly using gcc, but wouldn't using ccc/cxx.

BTW, sorry about not attaching that configure log sooner...  Work's been crazy.
 I'll try to get to it tonight.

Comment 5

[jim_nance]

Yes, sorry.  I was talking about Tru64

Comment 6

It looks like xptcall has only been ported to gcc for Linux/Alpha.  I don't know
of any working Linux/Alpha boxes, much less ones with the compaq compiler. 

At a glance, it may be possible to just copy the inline asm code into a separate
asm file.  The syntax looks like it should be the same, if the osf1 asm code is
any indication.

Comment 7

Attachment: Use existing osf1 asm files rather than inline asm

I found that the asm used for the osf1 build is identicalto the inline asm
code.	Give this patch a shot and see if it fixes the problem.  If xpcom
builds, can you verify that dist/bin/TestXPTCInvoke works?
