Fangrui Song	9c371309f3	[ELF][X86] Allow PT_LOAD to have overlapping p_offset ranges on EM_386 ... Ported the D64906 technique to EM_386. If `sh_addralign(.tdata) < sh_addralign(.tbss)`, we can potentially make `p_vaddr(PT_TLS)%p_align(PT_TLS) != 0`. ld.so that are known to have problems if p_vaddr%p_align!=0: * FreeBSD 13.0-CURRENT rtld-elf * glibc https://sourceware.org/bugzilla/show_bug.cgi?id=24606 New test i386-tls-vaddr-align.s checks our workaround makes p_vaddr%p_align = 0.

Dimitry Andric	c9de3b4d26	Align AArch64 and i386 image base to superpage ... Summary: As for x86_64, the default image base for AArch64 and i386 should be aligned to a superpage appropriate for the architecture. On AArch64, this is 2 MiB, on i386 it is 4 MiB.

George Rimar	11d09fc2f2	[ELF] - Add test case to test 32 bits output. ... We had no tests that checked how we print -Map output for 32 bit targets. Though there are at least 2 places where we have the difference. (between 64 and 32 bits): https://github.com/llvm-mirror/lld/blob/master/ELF/MapFile.cpp#L52 https://github.com/llvm-mirror/lld/blob/master/ELF/MapFile.cpp#L162 Patch adds just a trivial test to check we do right things in general. llvm-svn: 335954	2018-06-29 08:54:34 +00:00
