gcc.target/alpha/PR24178.c started to fail on mainline recently:
FAIL: gcc.target/alpha/pr24178.c scan-assembler ldl.*,18\\\\(
The problem is, that we don't generate expected ldl insn, but:
f:
.frame $30,0,$26,0
.prologue 0
lda $1,18($16)
ldq_u $0,18($16)
extbl $0,$1,$0
ret $31,($26),1
.end f
The generated code is similar to what PR24178 fixed, see PR24178, comment #9.
The testcase passed with r161055 [1] and failed with r161806 [2].
In between is Richi's mem-ref2 merge...
