Hi Andre,
Another feedback on your purecode patch.
You have to disable casesi pattern since then it will
generate wrong code with -mpure-code option.
Indeed it will generate an 'adr rx, .Lx' (aka
'subs rx, PC, #offset') which will not work in our
case since 'Lx' label is put in an .rodata sect
Hi Andre,
I think you have a typo in your patch. I need to change :
+text_section->unnamed.data = "\t.section
.text,\"0x2006\",%%progbits";
into
+text_section->unnamed.data = "\t.section
.text,\"0x2006\",%progbits";
to make it works.
Regards
Mickael

Hello,
This patch adds the -mpure-code option for ARM. This option ensures
functions are put into sections that contain only code and no data. To
ensure this throughout compilation we give these sections the ARM
processor-specific ELF section attribute "SHF_ARM_PURECODE". This option
is only suppo
