From f92bd43480bf2da36354e148d139ef2aac12d3f2 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 23 Aug 2022 17:04:16 +0100 Subject: target/arm: Remove useless TARGET_BIG_ENDIAN check in armv7m_load_kernel() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Arm system emulation targets always have TARGET_BIG_ENDIAN clear, so there is no need to have handling in armv7m_load_kernel() for the case when it is defined. Remove the unnecessary code. Side notes: * our M-profile implementation is always little-endian (that is, it makes the IMPDEF choice that the read-only AIRCR.ENDIANNESS is 0) * if we did want to handle big-endian ELF files here we should do it the way that hw/arm/boot.c:arm_load_elf() does, by looking at the ELF header to see what endianness the file itself is Signed-off-by: Peter Maydell Reviewed-by: Richard Henderson Reviewed-by: Philippe Mathieu-Daudé Message-Id: <20220823160417.3858216-2-peter.maydell@linaro.org> Signed-off-by: Richard Henderson --- hw/arm/armv7m.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'hw') diff --git a/hw/arm/armv7m.c b/hw/arm/armv7m.c index 990861e..fa4c2c7 100644 --- a/hw/arm/armv7m.c +++ b/hw/arm/armv7m.c @@ -572,17 +572,10 @@ void armv7m_load_kernel(ARMCPU *cpu, const char *kernel_filename, int mem_size) { ssize_t image_size; uint64_t entry; - int big_endian; AddressSpace *as; int asidx; CPUState *cs = CPU(cpu); -#if TARGET_BIG_ENDIAN - big_endian = 1; -#else - big_endian = 0; -#endif - if (arm_feature(&cpu->env, ARM_FEATURE_EL3)) { asidx = ARMASIdx_S; } else { @@ -593,7 +586,7 @@ void armv7m_load_kernel(ARMCPU *cpu, const char *kernel_filename, int mem_size) if (kernel_filename) { image_size = load_elf_as(kernel_filename, NULL, NULL, NULL, &entry, NULL, NULL, - NULL, big_endian, EM_ARM, 1, 0, as); + NULL, 0, EM_ARM, 1, 0, as); if (image_size < 0) { image_size = load_image_targphys_as(kernel_filename, 0, mem_size, as); -- cgit v1.1
