IEEE-754R defines a normal floating point number as: 2.1.38 normal number: For a particular format, a finite non-zero floating-point number with magnitude greater than or equal to a minimum bemin value, where b is the radix. Normal numbers can use the full precision available in a format. In this standard, zero is neither normal nor subnormal. This implies that a denormal is not a normal number.

...nt thing to have in your toolbox anyways since sometimes Intel's documentation can be non-specific).

All of our internal testers use LNT. LNT behind the scenes just calls the Makefiles appropriately. So it would be impossible to get rid of the makefile execution without gutting LNT as well = p. I will let Daniel comment on the rest of it. On Jan 3, 2013, at 6:55 PM, Renato Golin <renato.golin at linaro.org> wrote: > On 3 January 2013 16:37, David Blaikie <dblaikie at gmail.com>

(I said the same thing in my last email = p, except a bit more conservative: do a clean build after 3 failures or something along those lines).

There is currently no one publicly using the compile tests. We use it internally around the clock. I am not sure what Daniel's vision for the use of this externally (i.e. I am not sure how beta/non-beta he thinks this is), but regardless the way to use it is: 1. Create a directory. 2. Stick a bunch of tar balls you want into the directory. 3. Create a project_list.json file and write a
