powerpc -mcpu=common equivalent ?

[Daniel Walker]

Hi,


It looks like -mcpu=common (on the powerpc architecture) was removed. My 
group is struggling to find a way to compile generic binaries for 
PowerPC. We have been getting an LWSYNC instruction included in the 
binaries, and some of our processors are getting a trap when this 
instructions is executed. The platforms we are using are all Freescale, 
they are p2020, t1042, and 8540.

Freescale support informed us that we should use -mcpu=common , which is 
gone, we tried a number of other -mcpu setting including -mcpu=powerpc, 
but none of them allow us to have generic binaries for all the platforms.

I suppose this is either a bug report that we're getting lwsync when we 
shouldn't be getting it, or just a question of what the typical tune is 
to make generic binaries ?

Thanks for any help,

Daniel
