What I meant is that relative to some other (commonly used) routines within
dietlibc, printf and stroul are large in object size terms. I should have
written the above as two sentances.
The biggest things seem to be printf support, perror support, and strtoul.
__v_printf |080484b8| T | FUNC|00000773| |.text
__dtostr |08048cc7| T | FUNC|000003ae| |.text
sys_errlist |08049650| R | OBJECT|000001f8| |.rodata
__umoddi3 |08049400| T | FUNC|000001e5| |.text
__udivdi3 |080492c0| T | FUNC|0000013e| |.text
strtoul |080482f0| T | FUNC|0000010e| |.text
__lltostr |080490ec| T | FUNC|000000db| |.text
__ltostr |080491c8| T | FUNC|00000099| |.text
strtol |08048268| T | FUNC|00000086| |.text
perror |080481ec| T | FUNC|0000007a| |.text
compare to main:
main |080480bc| T | FUNC|000000d6| |.text
The dietlibc versions of the algorithms have generally been written to be
small, rather than fast.
