Subject: [PATCH] LF-7968-01 fix(Makefile): Suppress array-bounds error
|
||
|
|
|
||
|
|
The array-bounds error is triggered now in cases where it was silent
|
||
|
|
before, causing errors like:
|
||
|
|
|
||
|
|
```
|
||
|
|
plat/imx/imx8m/hab.c: In function 'imx_hab_handler':
|
||
|
|
plat/imx/imx8m/hab.c:64:57: error: array subscript 0 is outside array bounds of 'uint32_t[0]' {aka 'unsigned int[]'} [-Werror=array-bounds]
|
||
|
|
64 | #define HAB_RVT_CHECK_TARGET_ARM64 ((unsigned long)*(uint32_t *)(HAB_RVT_BASE + 0x18))
|
||
|
|
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
```
|
||
|
|
|
||
|
|
The error is a false-positive and is entered as a bug [1]. The problem
|
||
|
|
is fixed partially in GCC 12 and fully in GCC 13 [2].
|
||
|
|
|
||
|
|
The partial fix does not work here because the constant addresses used
|
||
|
|
are less than the 4kB boundary chosen for the partial fix, so suppress
|
||
|
|
the error until GCC is upgraded to 13.
