So it turns out that I was wrong. It, in fact, is not standard. But
regardless, you can use asm to specify the exact name. Eg.
extern int func() asm("func");

Despite the title of the thread, the solution is compiler and system
independent.

You were correct the first time. That post is talking about a Windows target. Ashi is working on iOS. Underscores are normal and expected. Using an "asm" name on the symbol is a horrible hack. Adding the underscore to the name in the .s file is the correct solution. -Jim On Feb 20, 2013, at 12:04 AM, Tyler Hardin <tghardin1 at catamount.wcu.edu> wrote:> So it turns out that I was wrong.

Hi, Jim, Why "asm" name is a horrible hack? Do you have any suggestion for cross-platform support of my ARM assembly code?
