[U-Boot] u-boot-2010.03 build errors with USE_PRIVATE_LIBGCC=yes option

throwing the following errors.

[U-Boot] u-boot-2010.03 build errors with USE_PRIVATE_LIBGCC=yes option

[Fabio Giovagnini]

I had a similar problem with sh2a 7203 based board and gcc version 4.4.1 
(Sourcery G++ Lite 4.4-206)
Verify if the undefined symbols are of libgcc.

Regards

They must be, because I can compile the source without USE_PRIVATE_LIBGCC=yes option
But due to a few constraints, I have to compile the code with USE_PRIVATE_LIBGCC=yes
option enabled

[U-Boot] u-boot-2010.03 build errors with USE_PRIVATE_LIBGCC=yes option

[Fabio Giovagnini]

Ciao Vipin,
ok, so the only way is to select the source file containing the fuction from 
libgcc and include at source level into your source u-boot tree.
I did the same but I started from the lib dir of linux kernel

Regards

Hmmm, I was just avoiding it thinking that maybe someone somewhere would have

Just for my info.
I did  USE_PRIVATE_LIBGCC=yes modifing directly the makfile.
Is iot possible to specify this in board dependent config file?

I'll send my patches as soon as i'll finish the porting on my boadl called 
mlcd7203

Why? Just pass it on the command line, or set it as envrionment
variable.

something like

Right?

Ok Thanks a lot

The problem why I was looking for this is that the tool-chain I am using only 
supports -mhard-float option and this toolchain is specifically meant for armv7 
(basically Cortex-A9 with FPU enabled).

Since this option -msoft-float is passed from arch/arm/cpu/config.mk, and it 
is common for all arm configurations. Is there a good way to pass -mhard-float..

Why would you want to do that? We don't use any FP code in U-Boot
anyway.

We have actually seen issues with the post memory tests using the -mfpu=neon
and -ftree-vectorize under gcc 4.4.1.  So, I would be very careful with FP
flags until someone figures out how to fix the 64-bit access operators that
the memory test uses.

Well, there _is_ a reason for using -msoft-float as we are doing in
U-Boot.  Thanks for confirming this again.
