Aries is the HP-UX PA-RISC to HP-UX IPF binary emulator. Aries
transparently emulates both 32-bit and 64-bit HP-UX PA-RISC applications
on HP-UX IPF.
The Aries distribution on HP-UX IPF system consists of four
shared libraries:
| /usr/lib/hpux32/aries32.so |
| /usr/lib/hpux32/pa_boot32.so |
| /usr/lib/hpux64/aries64.so |
| /usr/lib/hpux64/pa_boot64.so |
The HP-UX IPF kernel invokes pa_boot[32/64].so when a 32/64-bit PA-RISC binary is launched. Similarly, pa_boot[32/64].so invokes aries[32/64].so.
Summary
of Change |
 |
Aries is enhanced to allow the user to debug PA-RISC/HP-UX
applications running under compatibility mode under Aries on IPF/HP-UX
using PA-RISC/HP-UX gdb. Support for the generation of PA-RISC Core file on IPF
is also provided.
Details
of Change |
|
Aries emulates the ttrace system call in order to enable pa-gdb to run under Aries on IPF. Both 32 and 64-bit Aries incorporate
this support. In addition, Aries (both 32 and 64-bit) also generates
PA-RISC core dump when an emulated PA-RISC application fails on
IPF. Aries follows the exact semantics of PA-RISC HP-UX kernel while
creating the core file. Such a core file can be either analyzed
on an IPF system using emulated PA-RISC gdb or can be transferred to a PA-RISC machine and analyzed
using the native PA-RISC gdb.
This new Aries feature allows the user to transparently debug
PA-RISC/HP-UX applications running in compatibility mode under Aries
on IPF/HP-UX, using PA-RISC/HP-UX gdb. In this case, the PA-RISC/HP-UX gdb also runs on IPF/HP-UX platform in compatibility mode
under Aries.
Until now, Aries did not support emulation of debugger programs
like gdb belonging to the PA-RISC/HP-UX platform on IPF/HP-UX
platform. Any ttrace/ptracecall made by a program would fall under
Aries Limitation and fail. This feature helps the user to triage failures
of a PA-RISC/HP-UX application running under Aries on IPF/HP-UX
and find out the possible reasons of failure of the application.
Impact |
|
In HP-UX 11i v1.6 for IPF, the PA-RISC/HP-UX gdb is packaged under /usr/ccs/bin. Users are advised to add /usr/ccs/bin to the PATH environment variable. Also, in this release Native gdb is enhanced to detect PA-RISC/HP-UX executables and launch
them under the packaged PA-RISC/HP-UX gdb.
Compatibility |
|
No compatibility issues.
Performance |
|
No performance impact to the system and previous version of
Aries.
Obsolescence |
|
Not applicable.
Documentation |
|
The Aries manpage, aries(5), is updated with the necessary
technical and usage information relating to the new features.
