Already did.

Ok, and what's about -mthumb then?

Try -ccc-gcc-name arm-none-linux-gnueabi-g++ -ccc-host-triple
thumbv7m-none-linux-gnueabi
Sometimes it's better than sysroot, as it finds it

[LLVMdev] questions about ARM EABI attributes
...to clang:
$ clang -target armv7-linux-gnueabi -ffast-math (with -ffast-math)
.eabi_attribute 20, 2 @ Tag_ABI_FP_denormal
.eabi_attribute 23, 1 @ Tag_ABI_FP_number_model
$ clang -target armv7-linux-gnueabi (without -ffast-math)
.eabi_attribute 20, 1 @ Tag_ABI_FP_denormal
.eabi_attribute 21, 1 @ Tag_ABI_FP_exceptions
.eabi_attribute 23, 3 @ Tag_ABI_FP_number_model
Suppose there are two functions in a module which have different sets of
function attributes. One function has attributes for "-ffast-math" (foo1)
and the other (foo0) has attributes for "-fno-fast-math". In that case,
which s...

[ARM/Thumb] Make a function in arm while in Thumb triple
Hi,
I wanted to know if it was possible to force ARM backend to compile a
function in ARM while the rest is in Thumb mode.
I tried the attributes which is used in GCC but it doesn't work.
Here is what I tried:
