Subject: [PATCH] Only blacklist ARM gcc 4.8.0 and 4.8.1
|
||
|
|
|
||
|
|
Since many ARM toolchain providers include the bug fix for PR58854 in
|
||
|
|
their latest releases based on gcc-4.8.2, then only blacklist gcc 4.8.0
|
||
|
|
and 4.8.1.
|
||
|

/*

+ * Official gcc releases from 4.8.0 to 4.8.2 have the following bug,

|
|
+ * however, many arm toolchain providers have the included the fix for

|

|
|
+ * So, we only blacklist gcc 4.8.0 and 4.8.1.
|

|
|
+ * Unfortunately, this bug is not easy to test, so we rely on the

|
|
+ * knowledge of the user on its compiler.
