Details:
The __mul[hs]i_const_10 functions are defined in assembly, but these symbols'
types are unknown ("NOTYPE") in ELF object.
Example:
$ avr-readelf -s ~/install/avr/lib/avrxmega3/libc.a | grep "_const_10"
6: 00000000 0 NOTYPE GLOBAL DEFAULT UND __mulhi_const_10
6: 00000000 0 NOTYPE GLOBAL DEFAULT UND __mulsi_const_10
5: 00000000 0 NOTYPE GLOBAL DEFAULT 4 __mulsi_const_10
5: 00000000 0 NOTYPE GLOBAL DEFAULT 4 __mulhi_const_10
The attached patch updates these functions type and also adds .size
attribute.
Output after applying this patch:
$ avr-readelf -s ~/install/avr/lib/avrxmega3/libc.a | grep "_const_10"
6: 00000000 0 NOTYPE GLOBAL DEFAULT UND __mulhi_const_10
6: 00000000 0 NOTYPE GLOBAL DEFAULT UND __mulsi_const_10
5: 00000000 42 FUNC GLOBAL DEFAULT 4 __mulsi_const_10
5: 00000000 16 FUNC GLOBAL DEFAULT 4 __mulhi_const_10
