Hi maybe your proposal can be added. Here are the additional flags I use to compile SQLite on Windows which may also help if your application is single thread:
-DSQLITE_DQS=0 -DSQLITE_MEMORY_BARRIER="0" -DSQLITE_THREADSAFE=0 -DSQLITE_ENABLE_JSON1 From: Tinycc-devel [mailto:[email protected]] On Behalf Of Tyge Løvset Sent: Sunday, June 20, 2021 20:31 To: [email protected] Subject: [Tinycc-devel] sqlite on windows Hi, It works on Linux: tcc insert_data.c sqlite.c -pthread -ldl, but on win64 I get an undefined intrinsic symbol __faststorefence(). It can be implemented as an mfence instruction, but I think microsoft implements it with xchgl or similar, as below. Should we add this? #ifdef _WIN64 void __faststorefence(void) { long __fence; __asm__ __volatile__( "xchgl %%eax, %0" :"=m"(__fence)); //__asm__ __volatile__("mfence":::"memory"); } #endif
