APAR status

  • Closed as program error.

Error description

  • When using a high level of optimization (-qipa) with
    embedded assembler code, especially when coupled
    with -g option, linker time is significantly increased,
    due to the large number of debugger pseudo-op
    instructions.
    
    Change the way assembler pseudo-ops are handled.
    

Local fix

Problem summary

  • When the compiler generates an assembler source file (because
    of asm directives in the C/C++ source code) and the -g flag is
    used, the assembler can take a very long time.
    

Problem conclusion

  • Improve the performance of the assembler when the source file
    contains a large number of debugger-related pseudo-ops. Ignore
    invalid .line pseudo-ops so that assembly is successful.
    

Temporary fix
