safely used per-package when compiling programs. The same goes for

|

; TARGET_MUL_BUG: Whether or not to work around multiplication
|
||||
; instruction hardware bug when generating code for models where
|
||||
; it may be present. From the trouble report for Etrax 100 LX:
|
||||
; "A multiply operation may cause incorrect cache behaviour
|
||||
; under some specific circumstances. The problem can occur if
|
||||
; the instruction following the multiply instruction causes a
|
||||
; cache miss, and multiply operand 1 (source operand) bits
|
||||
; [31:27] matches the logical mapping of the mode register
|
||||
; address (0xb0....), and bits [9:2] of operand 1 matches the
|
||||
; TLB register address (0x258-0x25f). There is such a mapping
|
||||
; in kernel mode or when the MMU is off. Normally there is no
|
||||
; such mapping in user mode, and the problem will therefore
|
||||
; probably not occur in Linux user mode programs."
|
||||
;
|
||||
; We have no sure-fire way to know from within GCC that we're
|
||||
; compiling a user program. For example, -fpic/PIC is used in
|
||||
; libgcc which is linked into the kernel. However, the
|
||||
; workaround option -mno-mul-bug can be safely used per-package
|
||||
; when compiling programs. The same goes for general user-only
|
||||
; libraries such as glibc, since there's no user-space
|
||||
; driver-like program that gets a mapping of I/O registers (all
|
||||
; on the same page, including the TLB registers).
