- Authentication-results: sourceware.org; auth=none
In ILP32, GCC fails to merge pointer arithmetic into the addressing
mode of a load instruction, as
add w0, w0, w1, lsl 2
ldr w0, [x0]
is not equivalent to:
ldr w0, [x0, w1, lsl 2]
Shows the expected FAIL->XFAILs on aarch64-linux-gnu_ilp32, no
regressions on aarch64-linux-gnu.
gcc/testsuite:
<date> Charles Baylis <charles.baylis@linaro.org>
* gcc.target/aarch64/extend.c (ldr_uxtw): Add xfail for ilp32.
(ldr_uxtw0): Likewise.
(ldr_sxtw): Likewise.
(ldr_sxtw0): Likewise.
