From e7c71e24730ae07241980812c8b747963f216260 Mon Sep 17 00:00:00 2001 From: Michael Matz Date: Wed, 22 Nov 2017 17:57:43 +0100 Subject: tccasm: synch C and asm symtab tighter See testcase. The C and asm symtab are still separate, but integrated tighter: the asm labels are only synched at file end, not after each asm snippet (this fixes references from one to another asm block), the C and asm syms are synched both ways, so defining things in asm and refering from C, or the other way around works. In effect this model reflects what happens with GCC better. For this the asm labels aren't using the C label namespace anymore, but their own, which increases the size of each TokenSym by a pointer. --- tests/asm-c-connect-1.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 tests/asm-c-connect-1.c (limited to 'tests/asm-c-connect-1.c') diff --git a/tests/asm-c-connect-1.c b/tests/asm-c-connect-1.c new file mode 100644 index 0000000..3f7b010 --- /dev/null +++ b/tests/asm-c-connect-1.c @@ -0,0 +1,31 @@ +#include + +#if defined _WIN32 && !defined __TINYC__ +# define U "_" +#else +# define U +#endif + +const char str[] = "x1\n"; +#ifdef __x86_64__ +asm(U"x1: push %rbp; mov $"U"str, %rdi; call "U"printf; pop %rbp; ret"); +#elif defined (__i386__) +asm(U"x1: push $"U"str; call "U"printf; pop %eax; ret"); +#endif + +int main(int argc, char *argv[]) +{ + asm("call "U"x1"); + asm("call "U"x2"); + asm("call "U"x3"); + return 0; +} + +static +int x2(void) +{ + printf("x2\n"); + return 2; +} + +extern int x3(void); -- cgit v1.3.1
