| Subject: [PATCH 1/2] libasm: Fix one GCC7 -Wformat-truncation=2 warning. |
| |
| Make sure that if we have really lots of labels the tempsym doesn't get |
| truncated because it is too small to hold the whole name. |
| |
| This doesn't enable -Wformat-truncation=2 or fix other "issues" pointed |
| out by enabling this warning because there are currently some issues |
| with it. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79448 |
