[U-Boot-Users] How to understand GOT macro?
Hi,
This might not be a typical u-boot question but it appears in u-boot code. u-boot defines a macro as below: #define GOT(NAME) .L_ ##NAME (r14)
I think ## is used to change string to instruction parameter name. But what does .L_ stand for?
Thanks,
Frank

This is standard CPP use.

No. The `##' preprocessing operator is used to paste tokens together. RTFM (see section "Concatenation").
does .L_ stand for?
An arbitrary name for a local label?
