Update on shared memory coarrays
Hello world, here is an update for the coarray_native branch. TL;DR: New stuff and bugfixes, need help with testsuite integration. Toon's test case has provided the opportunity to fix numerous bugs; it now runs correctly. It can be found at http://moene.org/~toon/random-weather . Here's a list of the major changes since the last email: * According to popular demand, the library has been renamed cas_shared, and any references to "native coarrays" have been expunged (except for the branch name, which we cannot change). the directory under libgfortran has been moved to cas_shared and the prefix in the front end and library has been changed to cas (for coarray_shared). The option is also called -fcoarray=shared now. * Use of pthread_barrier_t and associated functions has been removed, so there is a chance that the library compiles on MacOS now. * STAT and ERRMSG have been implemented. So, generally, the branch seems to be in a usable state now. Major missing features at the moment are: * allocatable components in coarrays * teams * gcc testsuite integration and testcases Since I'd like to get the branch merged as quickly as possible, any help with the testsuite would be greatly appreciated. So, if you could give it a spin (especially to test if there are platforms where it does not bootstrap), that would be great. Nicolas
Re: [RFC] Increase libstdc++ line length to 100(?) columns

Nine pixels per character is not a lot (it's what VGA used), and you can't have any window decoration. With a good font and screen, it's doable. But if the screen isn't quite sharp, then I think you wouldn't be able to use portrait mode anymore.

Using a standard condensed monospace font of 9px, it has a width of 7px, 120 char would take up 940px fitting two windows in horizontal mode and one in vertical. 9px isn't fuzzy, and 8px variants are even narrower. Sure using square monospace fonts might not fit, but that is an unusual configuration and easily worked around by living with a non-square monospace font, or accepting occational line overflow. Remember nobody is suggesting every line should be that long, just allowing it to allow better structural indentation. 'Allan
