; Mips used to generate 'jumpy' debug line info around calls. The address
|
||
|
|
; calculation for each call to f1() would share the same line info so it would
|
||
|
|
; emit output of the form:
|
||
|
|
; .loc $first_call_location
|
||
|
|
; .. address calculation ..
|
||
|
|
; .. function call ..
|

|

; .. address calculation ..
|
