From 0de2420c4b023e644f91a409803fedfb235bfc0b Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 2 Mar 2019 12:31:04 -0700 Subject: [PATCH] Use memcpy in minimal_symbol_reader::install minimal_symbol_reader::install copies minsyms from the msym_bunch objects into the allocated memory. It seemed better to me to do this via memcpy, as that is frequently optimized in libc. gdb/ChangeLog 2019-03-15 Tom Tromey * minsyms.c (minimal_symbol_reader::install): Use memcpy. --- gdb/ChangeLog | 4 ++++ gdb/minsyms.c | 6 +++--- 2 files changed, 7 insertions(+), 3 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 581a4c6a5a..8ac4515e55 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,7 @@ +2019-03-15 Tom Tromey + + * minsyms.c (minimal_symbol_reader::install): Use memcpy. + 2019-03-15 Tom Tromey * objfiles.h (struct objfile_per_bfd_storage) : Now a diff --git a/gdb/minsyms.c b/gdb/minsyms.c index 88ff259349..93097b1845 100644 --- a/gdb/minsyms.c +++ b/gdb/minsyms.c @@ -1337,7 +1337,6 @@ build_minimal_symbol_hash_tables (struct objfile *objfile) void minimal_symbol_reader::install () { - int bindex; int mcount; struct msym_bunch *bunch; struct minimal_symbol *msymbols; @@ -1384,8 +1383,9 @@ minimal_symbol_reader::install () for (bunch = m_msym_bunch; bunch != NULL; bunch = bunch->next) { - for (bindex = 0; bindex < m_msym_bunch_index; bindex++, mcount++) - msymbols[mcount] = bunch->contents[bindex]; + memcpy (&msymbols[mcount], &bunch->contents[0], + m_msym_bunch_index * sizeof (struct minimal_symbol)); + mcount += m_msym_bunch_index; m_msym_bunch_index = BUNCH_SIZE; }
