To my knowledge, NetSurf does nothing special for this. I believe
Google serves the "mobile" versions of pages. It probably refuses that
to Firefox, because it should have JavaScript.

Forcing page display without JavaScript

Many web sites (e.g. Google Groups) now refuse to display pages unless
your browser has JavaScript enabled. The browsers Netsurf and Dillo
manage to get around this, displaying the pages anyway. I'm trying to
understand the mechanisms behind this so I could implement the same
capability in a CLI browser like w3m or write a plugin for Firefox that
would force page display while still having JavaScript disabled.

How does this display-denial work and how does Netsurf get around it?
What part of the Netsurf code should I be looking at?

[gccsdk] Unaligned data access vs pack(push...

I am attempting to compile LZ4 compression, and the working binary
doesn't get it's arithmetic right, decompressing declares corruption.
The warnings

warning: #pragma pack(push[, id], <n>) is not supported on this target
warning: #pragma pack(pop[, id], <n>) is not supported on this target

can be avoided by using -D__ARM_FEATURE_UNALIGNED but according to
http://infocenter.arm.com/help/topic/com.arm.doc.dui0472c/BABFDBCJ.html
this could be a problem for earlier than ARMv6 also.

I'm not keen on starting on C++ stuff, This is a fairly small project,
but requires manually configuring.

One other config question is wether we support hardware bit counting,
in case that means something to anyone?

TIA Ron M.

[gccsdk] [Bug 242] New: Segfault from asasm

http://www.riscos.info/bugzilla3/show_bug.cgi?id=242

Summary: Segfault from asasm
Product: GCC/GCCSDK
Version: other
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P1
Component: RISC OS-specific tools
AssignedTo: John.Tytgat@aaug.net
ReportedBy: gccsdk-bugzilla@markettos.org.uk
Estimated Hours: 0.0


I have a checkout of GCCSDK rev 5827 which is giving a segfault when I try to
assemble something. To reproduce this:

git clone git://github.com/caliston/ro-bootlinux.git
cd ro-bootlinux
git checkout 4e3b87b8f6
cd HAL
../../../gccsdk/cross/bin/asasm -o Messaging.o s/Messaging
Segmentation fault

I can't update to HEAD (5890) because that won't build either (build error
below).

gdb backtrace (I'm not entirely sure what's going on here):
