We can drop a device from the build only when it isn't referenced from
|
|
|
9ae3a8 |
code we build. References come in two forms: extern symbols, and qdev
|
|
|
9ae3a8 |
driver names.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Unresolved extern symbols pose no real danger, because they fail
|
|
|
9ae3a8 |
safely at link time. Note for the curious: the optimizer gets rid of
|
|
|
9ae3a8 |
the reference to isa_ide_init() in hw/i386/pc_piix.c.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Unresolved driver names get detected only at runtime, so we better be
|
|
|
9ae3a8 |
extra careful. There is just one occurence of either driver name
|
|
|
9ae3a8 |
outside the code dropped by this patch: "isa-ide" in hw/isa/pc87312.c.
|
|
|
9ae3a8 |
Compiled only when CONFIG_PC87312 is enabled. It isn't in our build.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
"cfi.pflash01" is already no-user. Drop it anyway, because it's easy
|
|
|
9ae3a8 |
and safe.
