From 6af3332a4cbd1ffbc81f74759ef7c5e1a87d2e10 Mon Sep 17 00:00:00 2001 From: Vincent Ren-Wei Chen Date: Tue, 17 Jan 2017 07:31:24 +0100 Subject: nds32: add NPTL/TLS, *context function, libm changes and code cleanup This commit includes following features. 1. Support NPTL/TLS 2. Add libm function which is used to handle FP rounding and excpetions (ex: fclrexcpt,fedisblxcpti,feenablxcpt... ) 3. Add *context function for operating user context (ex: setcontext,getcontext,makecontext... ) 4. Change the return flow from signal handler 5. Cleanup of old code The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1, which are related to timing accuracy. (math and locale tests are disabled) Signed-off-by: Vincent Ren-Wei Chen --- ldso/ldso/nds32/dl-sysdep.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'ldso/ldso/nds32/dl-sysdep.h') diff --git a/ldso/ldso/nds32/dl-sysdep.h b/ldso/ldso/nds32/dl-sysdep.h index c4a32ca71..5ff2aa9ae 100644 --- a/ldso/ldso/nds32/dl-sysdep.h +++ b/ldso/ldso/nds32/dl-sysdep.h @@ -57,7 +57,8 @@ unsigned long _dl_linux_resolver(struct elf_resolve * tpnt, int reloc_entry); ELF_RTYPE_CLASS_NOCOPY iff TYPE should not be allowed to resolve to one of the main executable's symbols, as for a COPY reloc. */ #define elf_machine_type_class(type) \ - ((((type) == R_NDS32_JMP_SLOT) * ELF_RTYPE_CLASS_PLT) \ + ((((type) == R_NDS32_JMP_SLOT || (type) == R_NDS32_TLS_TPOFF \ + || (type) == R_NDS32_TLS_DESC) * ELF_RTYPE_CLASS_PLT) \ | (((type) == R_NDS32_COPY) * ELF_RTYPE_CLASS_COPY)) /* Return the link-time address of _DYNAMIC.
