From f6e5b92d639a51a25cbb72f90a831d9dfa75df3b Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Tue, 9 Oct 2007 13:12:04 -0700 Subject: ELF Loader: Use physical addresses instead of virtual ones. This works in SE mode because the virtual and physical addresses specified for segments are the same. In Alpha, the LoadAddrMask is still necessary because the virtual and physical addresses are the same and apparently rely on the super page mechanism. All of the regressions pass. --HG-- extra : convert_revision : 45e49dec5002d64e541bc466c61a0f304af29ea5 --- src/base/loader/elf_object.cc | 22 +++++++++++----------- 1 file changed, 11 insertions(+), 11 deletions(-) (limited to 'src/base/loader/elf_object.cc') diff --git a/src/base/loader/elf_object.cc b/src/base/loader/elf_object.cc index 553723e74..653088c44 100644 --- a/src/base/loader/elf_object.cc +++ b/src/base/loader/elf_object.cc @@ -176,7 +176,7 @@ ElfObject::tryFile(const string &fname, int fd, size_t len, uint8_t *data) if(phdr.p_offset <= e_phoff && phdr.p_offset + phdr.p_filesz > e_phoff) { - result->_programHeaderTable = phdr.p_vaddr + e_phoff; + result->_programHeaderTable = phdr.p_paddr + e_phoff; break; } } @@ -261,28 +261,28 @@ ElfObject::ElfObject(const string &_filename, int _fd, continue; // Check to see if this segment contains the bss section. - if (phdr.p_vaddr <= bssSecStart && - phdr.p_vaddr + phdr.p_memsz > bssSecStart && + if (phdr.p_paddr <= bssSecStart && + phdr.p_paddr + phdr.p_memsz > bssSecStart && phdr.p_memsz - phdr.p_filesz > 0) { - bss.baseAddr = phdr.p_vaddr + phdr.p_filesz; + bss.baseAddr = phdr.p_paddr + phdr.p_filesz; bss.size = phdr.p_memsz - phdr.p_filesz; bss.fileImage = NULL; } // Check to see if this is the text or data segment - if (phdr.p_vaddr <= textSecStart && - phdr.p_vaddr + phdr.p_filesz > textSecStart) { - text.baseAddr = phdr.p_vaddr; + if (phdr.p_paddr <= textSecStart && + phdr.p_paddr + phdr.p_filesz > textSecStart) { + text.baseAddr = phdr.p_paddr; text.size = phdr.p_filesz; text.fileImage = fileData + phdr.p_offset; - } else if (phdr.p_vaddr <= dataSecStart && - phdr.p_vaddr + phdr.p_filesz > dataSecStart) { - data.baseAddr = phdr.p_vaddr; + } else if (phdr.p_paddr <= dataSecStart && + phdr.p_paddr + phdr.p_filesz > dataSecStart) { + data.baseAddr = phdr.p_paddr; data.size = phdr.p_filesz; data.fileImage = fileData + phdr.p_offset; } else { Segment extra; - extra.baseAddr = phdr.p_vaddr; + extra.baseAddr = phdr.p_paddr; extra.size = phdr.p_filesz; extra.fileImage = fileData + phdr.p_offset; extraSegments.push_back(extra); -- cgit v1.2.3
