Is there a way to adjust CFLAGS within an ECM file? I want to be able
to adjust the optimization levels of configurations, without changing
the rest of the CFLAGS when using ecosconfig. I don't want to have to
hand edit the .ecc file.
This is an example of what I want to do:
$ ecosconfig new pc_rltk8139
$ ecosconfig import file_that_modifies_optimization_to_O0.ecm
$ ecosconfig tree
$ make
Now the 'pc_rltk8139' target would be built with -O0 optimization. I
don't know what the contents of "file_that_modifies_optimization.ecm"
would be.
Any suggestions?
Mike

Take a look at:
http://ecos.sourceware.org/docs-latest/cdl-guide/language.values.html
In particular the first example after the table of operators, the
example in the section Functions, and the documentation for is_substr()

It seems, it exists the ECos way for that (to make it with own CDL
rule), but Unix way is just to filter that
I did prepare same NOOPTIM.ECM using 'sed' and then import it
ecosconfig new target
sed -ne '/CYGBLD_GLOBAL_CFLAGS {/,/^}/p' ecos.ecc |
sed -e '/# user_value/s/# //;s/-g -O2/-g -O0/;/#/d;/^$/d' >NOOPTIM.ECM
ecosconfig import NOOPTIM.ECM
ecosconfig resolve

The only way I've figured out is to use sed to modify the
ecos.ecc file just before the doing the "tree" command. I
always use a shellscript to create a new tree. Here's a sample
where I modify the CFLAGS value:
----------------------------------------------------------------------
#!/bin/bash
[ecosconfig new/add/remove stuff here]
# need to add -G0 option to compiler flags to fix the linker error:
# Unable to reach __RedBoot_IDLE_TAB_END__ (at 0x08013428) from the global pointer (at 0x0801b$
# hopefully, someday Altera will fix this bug...
sed 's/# user_value "-g -O3/user_value "-g -G0 -O3/g' <ecos.ecc >ecos.ecc.new
mv ecos.ecc ecos.ecc.orig
mv ecos.ecc.new ecos.ecc
ecosconfig tree
[more sed commands to fix problems in Makefile and .ldi files]
----------------------------------------------------------------------

I get this error while trying to import my .ecm file:
---------------------------------------------------------------------
option CYGBLD_GLOBAL_CFLAGS: error
invalid command name "requires"
The ecm file looks like this:
--------------------------------------
cdl_option CYGBLD_GLOBAL_CFLAGS {
requires { is_substr(CYGBLD_GLOBAL_CFLAGS, " -O2") }
};
Do .ecm files have the same commands as .cdl?
Thanks!
Mike

Ah, my error. I thought you wanted this in one of your .cdl files.
You probably need to add some cdl somewhere, something like
cdl_option CYGBLD_GLOBAL_CFLAGS_O2 {
display "Compile with -02"
default 0
no_define
requires { is_substr(CYGBLD_GLOBAL_CFLAGS, " -O2") }
}
And then in your .ecm file
cdl_option CYGBLD_GLOBAL_CFLAGS_O2 {
user_value 1
}
