So any concern on switch softfp to hard? Meanwhile, what compiler is being used for Maemo 5 build? Does it support Neon naturally?
And as you may know, so far, we had switch compiler to 4.5.0, so seemed it is also time to change those flags. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Thiago Macieira Sent: Thursday, August 05, 2010 12:09 PM To: Development for the MeeGo Project (discussion list) Subject: Re: [MeeGo-dev] ARM softfloat or hardfloat?

The N900 hardware (Cortex-A8) does support hard float. However, Maemo 5 builds with the Neon VFP but in soft-fp mode. That is, it uses the hardware for manipulating the floating point values, but parameters are passed in ARM GP registers. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Senior Product Manager - Nokia, Qt Development Frameworks PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 _______________________________________________ MeeGo-dev mailing list [email protected] http://lists.meego.com/listinfo/meego-dev
