From: Jose E. Marchesi Date: Mon, 30 Oct 2023 14:57:58 +0000 (+0100) Subject: gas: bpf: new test for MOV with C-like numbers ll suffix X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d3beaa140dd22316371f3ebb2570a215c800a46d;p=binutils-gdb.git gas: bpf: new test for MOV with C-like numbers ll suffix The BPF pseudo-c syntax supports both MOV and LDDW instructions: mov: r1 = EXPR lddw: r1 = EXPR ll Note that the white space between EXPR and `ll' is necessary in order to avoid ambiguity with the assembler's support for C-like numerical suffixes. This patch adds a new test to the GAS BPF testsuite to make sure that instructions like: r1 = 666ll are interpreted as `mov %r1,666', not as `lddw %r1,666'. This matches clang's assembler behavior. 2023-10-30 Jose E.
