18875 - HP aCC Optimized build on 11.00 coredumps

Status: VERIFIED FIXED

(SeaMonkey :: General, defect, P3)

Description

[Jim Dunn]

Building with --disable-debug --enable-optimize causes a coredump on startup

Comment 1

[Jim Dunn]

This can be fixed by NOT compiling xpcom/reflect/xptcall/src/md/unix/*.cpp 
with -O.

Comment 2

[Jim Dunn]

Bingo... I determined that compiling the CPP's with -O caused the problem

Check in... we probably want to revisit this at some point

Comment 4

[Jim Salter]

You want to look at the following for optimization options on HP:
  /opt/aCC/html/C/guide/optimize.htm

And you should look at compiling with the following flags, if you're not 
already:

-Ae +ESlit +Z +DAportable +DS2.0 -D_USE_BIG_FDS -D_POSIX_C_SOURCE=199506L

-Ae - ANSI C extended mode support, including:
          Long pointers
          Integral type specifiers can appear in enum declarations.
          The $ character can appear in identifier names.
          Missing parameters on intrinsic calls

+Z - Generates position-independent code (PIC) to go into a shared library

+ESlit - Place string literals and const-qualified data into read-only memory

+DAportable - generate code compatible across PA-RISC 1.1 and 2.0 systems

+DS2.0 - Use the instruction scheduler tuned to the model specified

-D_USE_BIG_FDS - change the maximum file open limit from 2048 to 60000 - see 
/usr/include/sys/_fd_macros.h

-D_POSIX_C_SOURCE=199506L - selects Posix 1c threads unless draft4 selected - 
see /usr/include/sys/stdsyms.h
