Ever since an old patch version, it has (for reasonable security reasons) not supported patched with ../ in the filename. Many of our patches have been relying on this behaviour being OK, because we start off with an ancient patch version that didn't perform such checks. As soon as we need this behaviour after we build a newer patch though, we will have problems. So, let's change the policy. Patches are relative to where tarballs are extracted, rather than the "working directory" - e.g. have patches for `coreutils-9.4/src/cp.c` instead of `src/cp.c`. Keeping this consistent has a few implications; - patches are applied from the build/ directory in bash era now, with `-p0` - when patches are manually applied in the bash era, use `-p` as required, usually `-p1` - in kaem era where patches are always manually applied, `-p1` is used

Subject: [PATCH 1/1] Don't fail on const/restrict/static/* inside []
|
|
|
|
This patch makes tcc ignore them.
|
|
|
|
Normally (as per the C standard), They should
|
|
be only applicable inside parameter arrays
|
|
and affect (const/restrict) the pointer the
|
|
array gets converted to.
|
|
|
|
[matz: fix formatting, add volatile handling, add testcase,
|
|
add comment about above deficiency]
