  1. POc99 inline semantics with gcc (mspgcc)
    text
    copied!<p>I am writing a couple of functions that I would like to inline.</p> <p>Reading <a href="http://www.greenend.org.uk/rjk/tech/inline.html" rel="nofollow">here</a> and using the second c99 inline option with inline on all declarations and definitions, like so:</p> <pre><code>extern inline void SPFD54124B_write_cmd(uint16_t command); </code></pre> <p>in a header, and</p> <pre><code>inline void SPFD54124B_write_cmd(uint16_t command) { spi_write(command, CMD_WIDTH); } </code></pre> <p>in a corresponding c file. I was expecting to get inlined versions of the functions.</p> <p>But when I compile i get:</p> <pre><code>Generating dependencies dep/spi.d from src/spi.c Generating dependencies dep/spfd54124b.d from
