Subject: [PATCH] Fix build on ARMv6.
|
|
|
|
The ARMv6 and older architures does not support the movw and movl
|
|
instructions, thus causing a build break.
|
|
This patch fix the problem by creating a new offlineasm instruction,
|
|
which will use the ldr instruction to load a immediate into a register.
