[LLVMdev] weak linkage
...rt on the ARM backend and I noticed this code on the X86 and PPC backends: ------------------------------------------------ // If the initializer is a extern weak symbol, remember to emit the weak // reference! if (const GlobalValue *GV = dyn_cast<GlobalValue>(C)) if (GV->hasExternalWeakLinkage()) ExtWeakSymbols.insert(Mang->getValueName(GV)); ------------------------------------------------ Can a initializer be a weak reference? For example, ------------------------ int a __attribute__ ((weak)); int b = a; ------------------------ fails to compile with the error: test.c:2: error...

[LLVMdev] [patch] arm: external weak in constant pool
Hi Lauro, Just a stylistic remark; In your "llvm.patch" file, there are tabs in these lines: + if (GV->hasExternalWeakLinkage()) { + ExtWeakSymbols.insert(GV); + } Others will need to review the patch for correctness, though. -bw On 12/20/06, Lauro Ramos Venancio <lauro.venancio at gmail.com> wrote: > Adds external weak symbols of constant pool to ExtWeakSymbols set. > > > Lauro > > _...

[LLVMdev] Incorrect loop optimization when building the Linux kernel
I was trying to build the Linux kernel with clang and observed a crash due to incorrect loop optimization: drivers/base/firmware_class.c extern struct builtin_fw __start_builtin_fw[]; extern struct builtin_fw __end_builtin_fw[]; static bool fw_get_builtin_firmware(struct firmware *fw, const char *name) { struct builtin_fw *b_fw; for (b_fw = __start_builtin_fw; b_fw !=

[LLVMdev] [patch] print ".weak" directive
The attached patch makes the ASM printer print the ".weak" directive when a weak symbol is added to a constant pool. I need something similar to it in order to bootstrap gcc on ARM. Any comments?
