Hi there, According to the latest EABI at http://infocenter.arm.com/help/topic/com.arm.doc.ihi0045d/IHI0045D_ABI_adden da.pdf, the new definition of Tag_ABI_HardFP_use is as below: Tag_ABI_HardFP_use, (=27), uleb128 0 The user intended that FP use should be implied by Tag_FP_arch 1 The user intended this code to execute on the single-precision variant derived from Tag_FP_arch 2 Reserved 3 The user intended that FP use should be implied by Tag_FP_arch (Note: This is a deprecated duplicate of the default encoded by 0) The attached patch intends to update gcc to conform this definition. Tested with GCC regression test, no regressions. Is it OK? BR, Terry 2015-01-14 Terry Guo <terry.guo@arm.com> * config/arm/arm.c (arm_file_start): Update the assignment of Tag_ABI_HardFP_use.
