Hi, I wanted to know if it was possible to force ARM backend to compile a function in ARM while the rest is in Thumb mode. I tried the attributes which is used in GCC but it doesn't work. Here is what I tried: https://pastebin.com/jCr5LPUY Thanks in advance, Uvekilledkenny -------------- next part -------------- An HTML attachment was scrubbed... URL:
