On ARM64/Ubuntu 14.04.1 with the stock gcc (Ubuntu/Linaro 4.8.2-19ubuntu1) I've experienced the following: 

First, I wrote a macro with inline assembly containing a .text directive followed by a static variable (still in the macro). Then, I expanded that macro multiple times. The generated assembly output contains a .data directive before the first variable declaration but not afterwards.

This caused problems with dynamically linking shared libraries in WebKit (https://bugs.webkit.org/show_bug.cgi?id=137434).
