From 42dabba6578e4b19037512d052fdc711c1349d6f Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 25 Apr 2023 11:18:49 +0200 Subject: RISC-V: test for expected / no unexpected symbols Both the temporary workaround for PR/gas 29940 and the existing special casing of GPRs in my_getSmallExpression() aren't really tested anywhere (i.e. with the workarounds remove testing would still succeed). Nor is there any test for uses of symbols with names matching GPRs, where such is permitted. Before altering how this is to be dealt with, install two testcases covering the expected behavior. (For now this includes only known affected insns; re-ordering of entries in riscv_opcodes[] could, however, yield more of them.) --- gas/testsuite/gas/riscv/reg-syms-C.d | 4 ++++ gas/testsuite/gas/riscv/reg-syms.d | 8 ++++++++ gas/testsuite/gas/riscv/reg-syms.s | 10 ++++++++++ 3 files changed, 22 insertions(+) create mode 100644 gas/testsuite/gas/riscv/reg-syms-C.d create mode 100644 gas/testsuite/gas/riscv/reg-syms.d create mode 100644 gas/testsuite/gas/riscv/reg-syms.s (limited to 'gas') diff --git a/gas/testsuite/gas/riscv/reg-syms-C.d b/gas/testsuite/gas/riscv/reg-syms-C.d new file mode 100644 index 0000000..3cc8400 --- /dev/null +++ b/gas/testsuite/gas/riscv/reg-syms-C.d @@ -0,0 +1,4 @@ +#as: -march=rv32ic +#source: reg-syms.s +#nm: -- +#dump: reg-syms.d diff --git a/gas/testsuite/gas/riscv/reg-syms.d b/gas/testsuite/gas/riscv/reg-syms.d new file mode 100644 index 0000000..c7f8ad8 --- /dev/null +++ b/gas/testsuite/gas/riscv/reg-syms.d @@ -0,0 +1,8 @@ +#as: -march=rv32i +#nm: -- + +0+ t start + +U x2 + +U x4 + +U x6 + +U x8 diff --git a/gas/testsuite/gas/riscv/reg-syms.s b/gas/testsuite/gas/riscv/reg-syms.s new file mode 100644 index 0000000..4748fbf --- /dev/null +++ b/gas/testsuite/gas/riscv/reg-syms.s @@ -0,0 +1,10 @@ + .text +start: + and x8, x8, x1 + j x2 + jal x3, x4 + lui x5, %hi(x6) + lw x7, %lo(x8)(x9) + sll x1, x1, x10 + sra x8, x8, x11 + srl x8, x8, x12 -- cgit v1.1
