Hi.

I note that when one runs nds code accessing

Code: Select all

isDSiMode()
didn't seem to help.

-Wconversion and libnds/include/*

Hi. While I had -Wconversion turned on for some debug build, I noticed that many of the libnds header files do not like that flag very much, but it also seem that they wouldn't require that much effort to support it. One key element to fix seems to be the definition of BIT(n) so that it produces an ...

What is .twl ?

Hello there. I am trying to recompile my homebrew with the latest devkitarm (r50, gcc-8.2.0)/libnds(1.7.3.1) I downloaded and I was surprised most of my tools inflated over 4MiB.

Re: devkitARM release 50

I note that devkitARM_r50 contains a curious warning message about use of __sync_synchronize(). It's a gcc built-in memory barrier which only emits a call to __sync_synchronize on platforms which don't have memory barrier instructions. In your case you can compile your code with -fno-threadsafe-sta...

Re: devkitARM release 50

I note that devkitARM_r50 contains a curious warning message about use of __sync_synchronize(). Do you know of any context that lead to that line to be present? Is there any multi-thread-capable platform that makes it meaningful ? Would I be safe for NDS to redefine __sync_synchronize() as an empty ...

Re: devkitARM release 47

ah ? apparently, this could be a candidate. (found through the huge "instructions for installing the Tools" link on the home page, if you ask ^^")

Installer link

Hmm… The link to sourceforge seems to send me back at the forums home page.

Could it be possible to update the link towards the appropriate file in https://github.com/devkitPro, or has the .Exe installer/updated disappeared during the switch to pacman ?

Looks like the performance are now comparable to the one in the "good old" implementation. Great job.

I've got some time to give that performance issue a look again. I'll grab the libfat 1.0.9 and keep you updated.
(looks like I'll also check the "notify new posts" box ^^")
