This patch adds support to gcc for the Fuchsia OS 
(https://fuchsia.googlesource.com/).

OK for mainline?

Thanks -

Josh

Is it PIC by default or really PIE by default?
Also how does this interact with the -fpie/-fPIE options?

Thanks,
Andrew

The intent was to make it PIE by default - I was mistakenly under the impression that this meant
building with -fpic/PIC, a la the android builds. Does this seem more reasonable:

#define CC1_SPEC "%{!fno-pic:%{!fno-PIC:%{!fpic:%{!fPIC:" \
                    "%{!fno-pie:%{!fno-PIE:%{!fpie:%{!fPIE: -fPIC}}}}}}}}"

?

Thanks -

Josh

Re: [PATCH] Add support for Fuchsia (OS)

[Josh Conner]

Sorry, that should have been:

#define CC1_SPEC "%{!fno-pic:%{!fno-PIC:%{!fpic:%{!fPIC:" \
                   "%{!fno-pie:%{!fno-PIE:%{!fpie:%{!fPIE: -fPIE}}}}}}}}"

(default to PIE, not PIC)

This will leave the default cpu as arm7tdmi.  Is that what you want?
It's fine if it is, but if not, you should consider setting
target_cpu_cname here as well.

R.

Once this is in, can you please suggest a news item for our
main page?

(You could cook a patch following https://gcc.gnu.org/about.html
or suggest wording or an HTML snippet, and I'll take it from there.)

Similarly, would be good to add this to gcc-7/changes.html.

Mmm, probably not. Thanks for pointing that out.
I've attached an updated patch addressing all of the concerns so far.

OK for mainline?
