From 220c410162ebece4fffa2912ed79e348d3731d77 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Fri, 9 Apr 2021 13:40:11 +0100 Subject: [PATCH] libiberty, Darwin : Fix simple-object LTO table for cross-endian case. We encapsulate streamed IR in three special sections with a table that describes their entries. The table is expected to be written with native endianness for the target, but for cross-endian cross- compilation the swapping was omitted. Fixed thus. Signed-off-by: Iain Sandoe libiberty/ChangeLog: * simple-object-mach-o.c (simple_object_mach_o_write_segment): Arrange to swap the LTO index tables where needed. --- libiberty/simple-object-mach-o.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/libiberty/simple-object-mach-o.c b/libiberty/simple-object-mach-o.c index aa5e0952fafb..72b69d19c216 100644 --- a/libiberty/simple-object-mach-o.c +++ b/libiberty/simple-object-mach-o.c @@ -1225,6 +1225,11 @@ simple_object_mach_o_write_segment (simple_object_write *sobj, int descriptor, index[4 * i] -= index[0]; index[0] = 0; + /* Swap the indices, if required. */ + + for (i = 0; i < (nsects_in * 4); ++i) + set_32 (&index[i], index[i]); + sechdr_offset += sechdrsize; /* Write out the section names. -- 2.47.2
