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 to 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)
This patch intends to update Binutils to follow above definition. A big
difference is there will be no "Tag_ABI_HardFP_use: SP and DP" when
"arm-none-eabi-readelf -A a.axf"
Tested with Binutils regression test. No regression. Is it OK?
BR,
Terry
