[android-porting] Re: Port Bionic to a new CPU

2020-12-28 Thread Chen Wang
hello, Jallen
I find this old email from out of this group, how about your progress? I 
wonder what's the risc chip you were working with? Because I'm studying how 
to port android to RISC-v.

[android-porting] [Question] debug bionic linker with gdb

2020-12-28 Thread Chen Wang
Hi, android team guys,
I am working on port aosp to other isa than arm/x86. When I am debugging 
bionic/linker, I find a strange question, that is the gdb can not get 
file/line info from the linker_main.c, but for other files in linker, it 
works as normal.
I am running qemu as gdb server and run gdb as client to connect to qemu 
remotely.
I confirm that all the source files are compiled with "-g" and I can see 
the linker executable contains debug info with objdump.
Why it's special for the linker_main.c? What should I do to handle this?
Thanks in adv.
