My problem is how to add the whitespace. The preprocessor seems to strip it. Consider this (test.S):
#define ENTRY(X) \ .global X##; \ X##:
ENTRY(foo) ENTRY(bar)
gcc -S test.S:
.global foo; foo: .global bar; bar:
For c4x-gcc, this has to be like this:
.global foo foo: .global bar bar:
Without the leading whitespace, .global is taken as a name of a label. Without the newline before the labels, they are not recognized (taken as comments).
How can I tell the preprocessor to emit spaces and newlines?
