From 30c30cdc0b2d0af7aa05048345f272de77aba6cb Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Mon, 24 Mar 2014 05:50:28 -0500 Subject: [PATCH 10/18] arm64: Align code and data to 8 bytes. Insufficient alignment seems to be the cause of relocation errors when linking large native code OCaml programs: (.text+0xc): relocation truncated to fit: R_AARCH64_LDST64_ABS_LO12_NC against symbol `camlOdoc_type' defined in .data section in odoc_type.o ../stdlib/stdlib.a(listLabels.o): In function `camlListLabels__entry': (.text+0x10): relocation truncated to fit: R_AARCH64_LDST64_ABS_LO12_NC against symbol `camlListLabels' defined in .data section in ../stdlib/stdlib.a(listLabels.o) PR#6283 http://caml.inria.fr/mantis/view.php?id=6283 --- asmcomp/arm64/emit.mlp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/asmcomp/arm64/emit.mlp b/asmcomp/arm64/emit.mlp index fc9649c..4e7c4b0 100644 --- a/asmcomp/arm64/emit.mlp +++ b/asmcomp/arm64/emit.mlp @@ -651,7 +651,7 @@ let fundecl fundecl = call_gc_sites := []; bound_error_sites := []; ` .text\n`; - ` .align 2\n`; + ` .align 3\n`; ` .globl {emit_symbol fundecl.fun_name}\n`; ` .type {emit_symbol fundecl.fun_name}, %function\n`; `{emit_symbol fundecl.fun_name}:\n`; @@ -692,6 +692,7 @@ let emit_item = function let data l = ` .data\n`; + ` .align 3\n`; List.iter emit_item l (* Beginning / end of an assembly file *) -- 2.3.1
