Subject: [PATCH] linux-user: ARM: Ignore immediate value for svc in thumb
|
|
mode
|
|
|
|
When running in thumb mode, Linux doesn't evaluate the immediate value
|
|
of the svc instruction, but instead just always assumes the syscall number
|
|
to be in r7.
|
|
|
|
This fixes executing go_bootstrap while building go for me.
