Hi, all,
When the help option --target-help is issued, the available items
for -march=X are supposed to be displayed automatically.
We need to complete -march= option design to perform such mechanism.

Hi, all,
The variadic function ABI implmentation of current nds32 port on trunk
is incompatible to the past Andes toolchains. Fixing it requires many
changes on the different files. I split these changes into several

Hi, all,
In the nds32 port, we are expecting the implementation in nds32.c
is going to gradually grow up. For the sake of future maintenance,
we decide to provide individual modules and then migrate some
implementation from nds32.c into the modules.
The following is a series of patches:

Hi,
There is a target specific optimization, called fp-as-gp optimization,
in the nds32 port. We are planning to make it as an individual pass.
By now we just move related implementation into nds32-fp-as-gp.c module.
Committed as Rev.212288.

Hi,
The multiple load/store instructions are provided by nds32 target and
some memory access behaviors are able to utilize such instuctions.
We use nds32-memory-manipulation.c module to hold those memory related
implementation.

Hi,
The module is prepared for future implementation of pipeline models.
In this patch we only add a few comment to describe its purpose.

Description:
Hi,
We provide a nds32-cost.c module to maintain some cost implementation
required by target hooks and macros. Currently we only migrate
nds32_rtx_costs()
and nds32_address_cost() into the module.

Hi,
Many external functions are used in predicates and constraints checking.
