Hi,
MIPS gcc version is 4.3.2
Today I saw that .so files of MIPS contain some undef symbols with
non-zero value
The few I saw are defined in libC
Wont this confuse dynamic linker of 4.3.2 ? ( i know that in 4.3.3.
, there is the STO_MIPS_PLT check which skip these. )
How does the dynamic linker ignore them during lookup ?
What is the purpose of these symbols ?
thanks
shankar
