"Malformed input " messages while compiling WiFi example

[deepikabhavnani]

Compiling Mbed-os WiFi example throws warnings as shown below, when compiled for "REALTEK_RTL8195AM".

Malformed input found when parsing ARMCC map: lib_wlan_mbed_arm.ar(rtk_wlan_if.o)
Malformed input found when parsing ARMCC map: lib_wlan_mbed_arm.ar(rtw_psk.o)
Malformed input found when parsing ARMCC map: lib_wlan_mbed_arm.ar(rtw_xmit.o)

Malformed input found when parsing ARMCC map: lib_wlan_mbed_arm.ar(Hal8195APwrSeq.o)

Steps to reproduce:

1. mbed compile -t ARM -m REALTEK_RTL8195AM

I reproduced this issue on a different board. It hapopens when building with a .ar file as input.
It's when parsing the map file in the following script:

 RE_OBJECT_ARMCC = r'(.+\.l)\((.+\.o)\)'
            test_re_obj_name = re.match(RE_OBJECT_ARMCC, line)

            if test_re_obj_name:
                object_name = test_re_obj_name.group(1) + '/' + \
                              test_re_obj_name.group(2)

                return '[lib]/' + object_name
            else:
                print "Malformed input found when parsing ARMCC map: %s" % line
                return '[misc]'

The script memmap.py searches for .o files and libraries in the form of .l files.
Since the input is .ar file, this message is printed. Note this is only on ARMCC ( I haven't checked IAR) and it doesn't affect the resulting ELF file.

Thanks for the detailed explanation @RonEld. Do you have a recommendation for correcting this? could we just add .ar to the list of matched extensions?

[RonEld]

Hi @theotherjimmy yes.
I did a quick and dirty fix:

RE_OBJECT_ARMCC = r'(.+\.l)\((.+\.o)\)'
            test_re_obj_name = re.match(RE_OBJECT_ARMCC, line)

            if test_re_obj_name:
                object_name = test_re_obj_name.group(1) + '/' + \
                              test_re_obj_name.group(2)

                return '[lib]/' + object_name
            else:
                RE_OBJECT_ARMCC = r'(.+\.ar)\((.+\.o)\)'
                test_re_obj_name = re.match(RE_OBJECT_ARMCC, line)

                if test_re_obj_name:
                    object_name = test_re_obj_name.group(1) + '/' + \
                                  test_re_obj_name.group(2)

                    return '[lib]/' + object_name
                else:
                    print "Malformed input found when parsing ARMCC map: %s" % line
                    return '[misc]'

But I believe we can have a better solution, with the regular expression seraching for r'(.+\.l)\((.+\.o)\)' or r'(.+\.ar)\((.+\.o)\)' in a single line

[theotherjimmy]

Yeah, I'll code that up. Just a sec

[theotherjimmy]

@RonEld Does this patch work for you?

It works for me 😄

[theotherjimmy]

It also moves the library from [misc] to it's name!

[RonEld]

Yes, this patch works for me as well

[theotherjimmy]

Awesome. I'll make the PR momentarily.

After running mbed compile --clean -t ARM -m UBLOX_EVK_ODIN_W2 -f for the mbed-os-example-wifi on the mbed-os-5.6-oob branch

[theotherjimmy]

And does the aforementioned PR fix them for you?

[yennster]

@theotherjimmy yes it does!
