Tool/software: Code Composer Studio

I have no issue when building projects with the TI compiler:

   CSS
      Target: TMS570LC43xx
      Compiler version: TI v18.1.5.LTS

   HALCoGen
      Tools: Texas Instruments Tools
      Family: TMS570LC43x
      Device: TMS570LC4357ZWT

However when I switch to the GNU compiler, I have the following errors:

   ../source/HL_sys_core.s:98: Error: selected processor does not support `fmxr fpexc,r2' in ARM mode
   ../source/HL_sys_core.s:100: Error: selected processor does not support `fmdrr d0,r1,r1' in ARM mode
   ../source/HL_sys_core.s:101: Error: selected processor does not support `fmdrr d1,r1,r1' in ARM mode
   ../source/HL_sys_core.s:102: Error: selected processor does not support `fmdrr d2,r1,r1' in ARM mode
   ../source/HL_sys_core.s:103: Error: selected processor does not support `fmdrr d3,r1,r1' in ARM mode
   ...

Here is my GNU project setup:

   CSS
      Target: TMS570LC43xx
      Compiler version: GNU v7.2.1 (Linaro)

   HALCoGen
      Tools: GCC Tools
      Family: TMS570LC43x
      Device: TMS570LC4357ZWT
