[GAS, ARM] Invalid LDR immediate transformation
2015-11-24 Christophe Monat <christophe.monat@st.com>
* config/tc-arm.c (move_or_literal_pool): Do not transform ldr
ri,=imm into movs when ri is a high register in T1.
2015-11-24 Christophe Monat <christophe.monat@st.com>
* gas/arm/thumb2_ldr_immediate_armv6t2.s: Added high register
tests.
* gas/arm/thumb2_ldr_immediate_armv6t2.d: Accounted for new test
cases.
* gas/arm/thumb2_ldr_immediate_highregs_armv6t2.s: New.
* gas/arm/thumb2_ldr_immediate_highregs_armv6t2.d: New.
