Thanks. If anybody sees any breakage then please shout.
Hi Will,

In the libstdc++ tetsuite I'm seeing some failures of the sort:

/arm-none-eabi/install/arm-none-eabi/bin/ld: warning: address of
`text-segment' isn't multiple of maximum page size

FAIL: 17_intro/ (test for excess errors)

I haven't dug into it yet, but your patch is the first that came to mind
when seeing this.
Is that a problem in gcc/libstdc++?
I'm not sure, but it would be interesting to find out. Do you have any
more information e.g. command line or linker script being used?

Hi Will,
Sorry for the delay. The warning I was seeing was due to some bare-metal specs files that I was using placing the text segment at a non-64k-aligned position.
That's not a problem with this patch.


It seems that building libstdc++ involves building the whole of gcc. :-/
