Dear tinycc-devel,
A few more fixes for your review.
- support for generating ARM64 PE32+ images
- support for generating X64, ARM64, IA32 (untested) and ARM (untested)
UEFI images.
I don't think we want relocation entries by default in x86/x86-64
executables. Maybe you can support -Wl,-no-strip-base-relocs
Also pe32.h and the longish portions with IMAGE_SUBSYSTEM_*/IMAGE_FILE_*
produce lots of visual clutter. Maybe for something that changes once
in 10 years, we can use just hex numbers as before.
Other than that the patch seems to make sense. On which system did
you test this?

The UEFI stuff was tested by building the following simple app (you need
Tiano edk2 for the headers).
$ ./x86_64-win32-tcc -I ../edk2/MdePkg/Include/ -I
../edk2/MdePkg/Include/X64/ ../efitest.c -Wl,-subsystem=efiapp -nostdlib
-o ../efitest.x64.efi -v
$ ./arm64-win32-tcc -I ../edk2/MdePkg/Include/ -I
../edk2/MdePkg/Include/AArch64/ ../efitest.c -Wl,-subsystem=efiapp
-nostdlib -o ../efitest.aa64.efi
-->
#include <Uefi.h>
CHAR16 *gHello = L"Hello from a TinyCC compiled UEFI binary!\r\n";
EFI_STATUS EFIAPI
_start(EFI_HANDLE Handle,
EFI_SYSTEM_TABLE *SystemTable)
{
CHAR16 *StackString = L"String pointer on the stack\r\n";
SystemTable->ConOut->OutputString(SystemTable->ConOut, StackString);
SystemTable->ConOut->OutputString(SystemTable->ConOut, gHello);
return EFI_SUCCESS;
}
