Bug ID: 18763
Summary: [powerpc-darwin] default cpusubtype inconsistent with
system gcc
Product: clang
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Driver
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
On powerpc-darwin8 (triple: powerpc-apple-darwin8), clang -no-integrated-as
-save-temps emits ".machine ppc7400" by default, whereas system gcc (4.0) emits
".machine ppc" (cpusubtype:ALL). As much as I like having ppc7400 code running
on my G4, Iain feels this is incorrect, that for darwin8, the default should
either be 'ppc' (ALL) or 'ppc750' (G3). This explains the difference between
integrated and no-integrated-as I observe in bug 18463.
On darwin9, however, defaulting to .machine ppc7400 is acceptable (current
state).
