Is GCC >= 3.1 available for ELDK ? (or other means to compile Ada code)

Is GCC >= 3.1 available for ELDK ? (or other means to compile Ada code)

[ARIBAUD Albert]

Hi,

Here at work I've been asked to get some Ada code ported on an embedded, MPC855T-based platform using ELDK 2.02.

By the look of it, there are no major risks with repsect to the scheduler or libraries or performance; the only problem is getting to compile Ada code.

GCC supports Ada from version 3.1.1 up, but ELDK 2.0.2 features 2.95.4.

Is there a version of GCC >= 3.1.1 prepackaged for ELDK?

Thanks in advance,

Albert.

Short answer - no.

The ELDK still contains the reliable 2.95.4 compiler + associated
binutils because there were several problems with the >=3.0 toolchains
on the ppc platform.  To check the situation, I recently compiled gcc
3.2.2 + binutils 2.13 as a cross-compiler for the 8xx platform without
major problems out of the box.  A linux kernel compiled with the setup
ran with no noticeable difficulties so I am pretty confident that
the setup is stable for that platform.

The only reason that there is no pre-packaged gcc >= 3.1 for the ELDK
is the well known 24h/day limit and the fact that no customer demanded
a newer gcc as yet.

Hope that helps

Hi,

Does anybody know where I can get the document or manual about PowerPC assembly language ("as") ?

Thanks in advance!

Regards,
Zhou

Hi John,


Here is a good starting point

http://www-106.ibm.com/developerworks/library/l-ppc/?t=gr,lnxw09=PowPC

Here is an IBM PDF file (600+ page book) on PowerPC assembly lang

http://www-3.ibm.com/chips/techlib/techlib.nsf/techdocs/852569B20050FF778525699600719DF2

Here is an IBM PDF compiler writers guide on PPC asm tuning etc.

http://www-3.ibm.com/chips/techlib/techlib.nsf/techdocs/852569B20050FF7785256996007558C6


Here is a good starting point for Linux based asm (mostly x86)
http://linuxassembly.org/


	The most useful thing I can recomend is using these books/guides as a
reference and compiling c source code with the GCC flag  --save-temps to
generate assembly source from c code. This not only gives you a good
idea of what the assembly code is doing, but lets you analyze and refine
your C coding technique and practices to generate the best code.

Good Luck

Conn

Tha info pages for the GNU  assembler  "as"  are  installed  on  your
system.

The native "as" info files can be found in /usr/share/info/as.info*

If you installed the ELDK in the default  directory  (/opt/eldk)  you
can  find  the  versions  for  the  cross  assembler  for  example in
/opt/eldk/ppc_8xx/usr/share/info/as.info*

Note however that this is not  a  "manual"  about  "PowerPC  assembly
language".


As where to find this -  did  you  by  any  chance  enter  the  words
"PowerPC assembly language" into Google search?
